Versuchsvorschrift

The same operation as in Example (91c) was performed using 4-chloro-5-ethyl-1H-imidazole-2-carboxylic acid (0.12 g, 0.69 mmol), thionyl chloride (4 mL), methyl 4-amino-3-methylphenyl)-1,3-oxazole-4-carboxylate obtained in Example (109e) (0.23 g, 0.95 mmol) and pyridine (5 mL), to obtain 135 mg of the title compound as a light brown solid (50%).
