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, 0.256 mmol), thionyl chloride (2.0 mL), 3-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 0.015 g of the desired product. 1HNMR (DMSO-d6): δ 1.61 (s, 6H), 3.46 (s, 2H), 3.56 (s, 3H), 7.00 (m, 1H), 7.20 (m, 2H), 7.28 (d, 2H), 7.28 (d, 1H), 7.45 (d, 1H), 7.56 (t, 1H), 7.75 (d, J=7.2 Hz, 1H), 8.31 (s, 1H), 9.98 (s, 1H), 10.51 (s, 1H); MS [M+H]+: 533.27.
