Procedure

An amidation reaction and post-treatment were carried out according to the conditions of Example 1, using 2.2 g (10 mmol) of 4-amino-1-benzyl-5-imidazolecarboxamide prepared in Reference Example 2 and 2-methoxybenzoyl chloride separately prepared according to a conventional method, instead of benzoyl chloride, to obtain a crude amide product. The crude amide product was purified by suspension in hot methanol to obtain 1.87 g of 4-(2-methoxybenzoylamino)-1-benzyl-5-imidazolecarboxamide (yield 53%).
