Reaction Steps

The title compound was prepared by following the procedure 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, 0.273 g, 0.736 mmol), thionyl chloride (2.0 mL), 3-(1,1-difluoroethyl)aniline (Intermediate-39, 0.120 g, 0.736 mmol), THF (5.0 mL) and DIPEA (3 mL). The obtained crude product was purified by column chromatography on basic alumina eluting with 0.7-1.0% MeOH:DCM to afford 0.025 g of the desired product. 1HNMR (DMSO d6): δ 1.57 (s, 6H), 1.97 (t, J=19.2 Hz, 3H), 3.10 (s, 2H), 7.26-7.32 (m, 3H), 7.35-7.48 (m, 3H), 7.62 (d, J=8.4 Hz, 1H), 8.07 (s, 1H), 9.85 (s, 1H), 11.00 (s, 2H); MS [M−H]−: 513.14.
