Reaction Steps

The title compound was prepared by following the procedure as described for Example-108 using 2-((2-chloro-6-fluorophenyl)amino)-1,7,7-trimethyl-7,8-dihydro-1H-benzofuro[4,5-d]imidazole-5-carboxylic acid (Intermediate-49, 0.100 g, 0.2564 mmol), thionyl chloride (2.0 mL), 4-trifluoromethyl aniline (0.124 g, 0.769 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 0.010 g of the desired product. 1HNMR (DMSO-d6): δ 1.61 (s, 6H), 3.47 (s, 3H), 3.56 (s, 2H), 7.17-7.01 (m, 1H), 7.21 (bs, 2H), 7.29 (d, J=8.4 Hz, 1H), 7.70 (d, J=8.4 Hz, 2H), 7.90 (d, J=7.8 Hz, 2H), 9.92 (bs, 1H), 10.52 (bs, 1H): MS [M+H]+: 533.25.
