DESCRIPTION TECHNICAL FIELD The present invention relates to a method for producing a 2-chlorine atom or 2-bromine atom -4- nitroimidazole compound. BACKGROUND ART A 4-nitroimidazole compound represented by the following general formula (1): wherein X2 represents a chlorine atom or bromine atom, is useful as a synthetic intermediate used for producing various pharmaceuticals and agricultural chemicals, and particularly used for producing antitubercular agents. For example, methods represented by the following Reaction scheme-1 and -2 have previously been known as methods for producing the 4-nitroimidazole compound represented by general formula (1) (Jerzy Suwinski, Ewa Salwinska, Jan Watras, and Maria Widel, Polish Journal of Chemistry, 56, 1261-1272 (1982)). wherein XA represents a halogen atom. However, these methods have various disadvantages, and thus, are not adequate as production methods that are industrially applied. For example, in the method represented by Reaction scheme-1, compounds (6) and (7) that are reaction intermediates are chemically unstable, and there is a risk that these compounds may explode due to impacts such as fall or friction. In addition, in this method, the temperature applied during the reaction to obtain the compound (7) from the compound (6) by- heating (approximately 130°C) exceeds the TNR (Temperature of No Return; the maximal temperature ranging from 60°C to 70°C, at which the compound can safely be handled in a chemical processing apparatus) of the compound (6). Thus, it has been extremely dangerous to industrially produce the compound of interest in high volume by this method. The method represented by Reaction scheme-2 involves a reaction of nitrating the compound (8). However, the compound (1a) can be obtained only at low yield by such nitration, and thus, this method is industrially disadvantageous. DISCLOSURE OF THE INVENTION It is an object of the present invention to provide a method for producing a 4-nitroimidazole compound represented by general formula (1) at high yield and at high purity by a safer method causing few dangers such as explosion. In order to achieve the aforementioned object, the present inventors have conducted intensive studies regarding a method for producing a 4- nitroimidazole compound represented by general formula (1) . As a result, the present inventors have found that the aforementioned object can be achieved by selectively substituting a chlorine atom or bromine atom at position 5 of a 4-nitroimidazole compound represented by general formula (2) indicated below with an iodine atom, and then selectively reducing position 5 of the obtained 5-iodo-4-nitroimidazole compound represented by general formula (3) indicated below. That is to say, the present inventors have found that a 4-nitroimidazole compound represented by general formula (1) can be produced at high yield and at high purity by a safe method causing few dangers such as explosion, which comprises selectively substituting a chlorine atom or bromine atom at position 5 of a 4- nitroimidazole compound represented by general formula (2) indicated below with an iodine atom, and then selectively reducing position 5 of the obtained 5-iodo- 4-nitroimidazole compound represented by general formula (3) indicated below.
