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)-5-methyl-1,3-oxazole-4-carboxylate obtained in Example (102e) (90 mg, 0.21 mmol), 2 N lithium hydroxide (3 mL, 6 mmol), methanol (3 mL) and tetrahydrofuran (3 mL), to obtain 74 mg of the title compound as a light pink solid (85%).
