Procedure

The same operation as in Example (91c) was performed using 4-chloro-5-ethyl-1H-imidazole-2-carboxylic acid (0.18 g, 1.03 mmol), thionyl chloride (4 mL), methyl 4-amino-3-methylphenyl)-5-methyl-1,3-oxazole-4-carboxylate obtained in Example (108e) (0.28 g, 1.14 mmol) and pyridine (5 mL), to obtain 0.32 g of the title compound as a colorless solid (77%).
