Reaction Steps

Add 2-ethyl-butyryl chloride (0.014 g, 0.108 mmol) dropwise under an atmosphere of nitrogen to a 0° C. cooled solution of (S)-(3,5-bis-trifluoromethyl-benzyl)-(2-methyl-2H-tetrazol-5-yl)-(7-methyl-8-trifluoromethyl-2,3,4,5-tetrahydro-1H-benzo[b]azepin-5-yl)-amine (Example 3, Step 18) (0.060 g, 0.108 mmol) and pyridine (0.010 g, 0.108 mmol) in methylene chloride (5 mL). After stirring for 1 h, wash the reaction with saturated aqueous sodium bicarbonate solution (10 mL), 2N aqueous hydrogen chloride solution (10 mL), and brine (10 mL). Dry the organic layer over anhydrous sodium sulfate, filter, and concentrate under reduced pressure to afford the title compound as a colorless gum (0.075 g, 98%). 1H NMR (CDCl3, 300 MHz) δ 0.71-2.16 (m, 16H), 2.34-2.43 (m, 1H), 2.43 (s, 3H), 2.50-2.41 (m, 1H), 4.14 (s, 3H), 4.25-4.67 (m, 2H), 6.89 (bs, 1H), 7.43 (s, 1H), 7.75 (s, 2H), 7.85 (s, 1H); ESI MS m/z 651 [C29H31F9N6O+H]+.
