In the same manner as that described in Example 2(1), a reaction was carried out using commercially available 2-aminothiazole (333 mg, 3.3 mmol), N,N-diisopropylethylamine (1.21 ml, 7.0 mmol), 4-formylbenzoyl chloride (468 mg, 2.8 mmol) and 4-(dimethylamino)pyridine (a catalytic amount) and the reaction mixture was treated according to a similar procedure to that described in Example 2(1) to afford 4-formyl-N-(2-thiazolyl)benzamide (355 mg, yield 55%) as a pale yellow solid which was recrystallized from ethyl acetate-hexane to give pale yellow powdery crystals.
