Participants

Reaction Steps

The title compound was prepared by following the same procedure as described for Example-108 using 2-[(2-chloro-6-fluorophenyl)amino]-7,7-dimethyl-7,8-dihydro-1H-furo[3,2-e]benzimidazole-5-carboxylic acid (Intermediate-15, 0.150 g, 0.400 mmol), thionyl chloride (2.0 mL), 5-(difluoromethyl)-2-fluoroaniline (Intermediate-46, 0.097 g, 0.600 mmol), THF (5.0 mL) and DIPEA (2 mL). The obtained crude product was purified by column chromatography on basic alumina eluting with 0.7-1.0% MeOH:DCM to afford 0.012 g of the desired product. 1HNMR (DMSO-d6): δ 1.56 (s, 6H), 3.13 (s, 2H), 7.07 (t, J=55.5 Hz, 1H), 7.33-7.52 (m, 6H), 8.76 (d, J=6.9 Hz, 1H), 10.24 (s, 1H), 11.20 (s, 2H); MS [M+H]+: 519.20.
