Participants

Conditions

Temperature: 110 °C

Procedure

Tsunoda reagent (904 mg, 3.74 mmol) was added to a stirred suspension of methyl 2-[(4-carbamoyl-2-methylphenyl)amino]-4-chloro-1-(3-hydroxypropyl)-1H-benzimidazole-7-carboxylate (1.30 g, 3.12 mmol) in dichlorobenzene (30 mL) at room temperature, and the mixture was stirred at 110° C. for 23 hr. The mixture was concentrated in vacuo, crystallized from ethyl acetate/diisopropyl ether and washed with diisopropyl ether to give the title compound as a pale yellow powder (761 mg, 1.91 mmol, 61%).
