Ethyl 4-oxocyclohexanecarboxylate → (S)-4-(5-[(3,5-Bis-trifluoromethyl-benzyl)-(2-methyl-2H-tetrazol-5-yl)-amino]-7-methyl-8-trifluoromethyl-2,3,4,5-tetrahydro-benzo[b]azepin-1-yl}-cyclohexanecarboxylic acid ethyl ester

Participants

Reaction Steps

Prepare the title compound by essentially following the procedures described in the synthesis of (S)-(3,5-Bistrifluoromethylbenzyl)-(1-cyclopentylmethyl-7-methyl-8-trifluoromethyl-2,3,4,5-tetrahydro-1H-benzo[b]azepin-5-yl)-(2-methyl-2H-tetrazol-5-yl)amine (Example 3 step 19) by replacing cyclopentanecarboxaldehyde with 4-oxo-cyclohexanecarboxylic acid ethyl ester. Isolate the title compound by chromatography over silica gel, eluting with ethyl acetate/hexane. MS (ES+): 707 (M+H).
