Participants

Reaction Steps

The same operation as in Example (91d) was performed using methyl 2-(4-{[(4-chloro-5-ethyl-1H-imidazol-2-yl)carbonyl]amino}-3-methoxyphenyl)-1,3-oxazole-4-carboxylate obtained in Example (102e) (0.26 g, 0.64 mmol), 2 N lithium hydroxide (3 mL, 6 mmol), methanol (3 mL) and tetrahydrofuran (5 mL), to obtain 156 mg of the title compound as a colorless solid (62%).
