Reaction Steps

Prepare the title compound by essentially following the procedure described in the synthesis of (S)-(3-fluoro-5-trifluoromethyl-benzyl)-(7-methyl-1-pyridin-4-ylmethyl-8-trifluoromethyl-2,3,4,5-tetrahydro-1H-benzo[b]azepin-5-yl)-(2-methyl-2H-tetrazol-5-yl)-amine (Example 186, Step 2) by using (S)-(3-chloro-5-trifluoromethyl-benzyl)-(7,9-dimethyl-8-trifluoromethyl-2,3,4,5-tetrahydro-1H-benzo[b]azepin-5-yl)-(2-methyl-2H-tetrazol-5-yl)-amine (0.08 g, 0.15 mmol) and pyridine-4-carboxaldehyde (0.045 mL, 0.45 mmol) in dichloroethane (2 mL) at room temperature for 15 h to afford the title compound. Purification by silica gel column (gradient eluent, 0-5% MeOH in ethyl acetate) provides the title compound (0.09 g, 91%). MS (ES+): 624 (M+H).
