Procedure

The title compound was prepared following the procedure described for Example-137 by using methyl 2-[(3,5-dichloropyridin-4-yl)amino]-7,7-dimethyl-7,8-dihydro-1H-furo[3,2-e]benzimidazole-5-carboxylate (Step-1 of Intermediate-3, 0.100 g, 0.245 mmol), 2,3,4-trifluoroaniline (0.078 g, 0.530 mmol), trimethyl aluminium (2M solution in toluene) (0.5 mL), dry toluene (5.0 mL) at room temperature to afford 0.075 g of the desired product. 1HNMR (DMSO-d6): δ 1.57 (s, 6H), 3.09 (s, 2H), 7.28-7.39 (m, 2H), 8.15 (m, 1H), 8.45 (s, 2H), 9.92 (s, 1H), 11.02 (br s, 1H), 11.58 (br s, 1H); MS [M+H]+: 521.93.
