반응 단계
Ethyl 2-(2,4-dichlorophenyl)-4-methylthiazole-5-carboxylate (250 mg) prepared in the Step 23-1-1 was dissolved in ethanol (10 ml), and hydrazine monohydrate (794 mg) was added thereto. The mixture was heated under reflux for 23 hours. After the mixture was allowed to cool, the precipitated crystal was separated by filtration, washed with water, and dried to give 2-(2,4-dichlorophenyl)-4-methylthiazole-5-carboxylic acid hydrazide (211 mg, 88%).
