Reaction Steps

The title compound was prepared by following the procedure described for Example-108 using 2-[(2-chloro-5-methylphenyl)amino]-7,7-dimethyl-7,8-dihydro-1H-furo[3,2-e]benzimidazole-5-carboxylic acid (Intermediate-27, 0.175 g, 0.471 mmol), thionyl chloride (2.0 mL), 3-trifluoromethyl phenyl amine (0.114 g, 0.707 mmol), THF (5.0 mL) and DIPEA (2 mL). The obtained crude product was purified by column chromatography on neutral alumina eluting with 0.9% MeOH:DCM to afford 0.040 g of the desired product. 1HNMR (DMSO-d6): δ 1.61 (s, 6H), 2.33 (s, 3H), 3.16 (d, J=5.4 Hz, 2H), 6.87-6.88 (m, 1H), 7.35 (d, J=8.4 Hz, 1H), 7.44 (d, J=7.2 Hz, 1H), 7.60 (t, J=7.8 Hz, 1H), 7.73 (s, 1H), 7.78 (d, J=7.8 Hz, 1H), 8.34 (s, 2H), 9.00 (s, 1H), 10.01 (s, 1H), 10.05 (s, 1H); MS [M+H]+: 515.22.
