Reaction Steps

To a solution of 2-{[(3,5-bis-trifluoromethyl-benzyl)-(2-methyl-2H-tetrazol-5-yl)-amino]-methyl}-4-trifluoromethyl-benzaldehyde (244 mg, 0.48 mmoles) in THF (3 mL) at 0° C. was added cyclohexylmagnesium bromide (18% solution in THF, 0.6 mL, 0.57 mmoles) and the reaction was allow to warm to room temperature and stirred overnight. The reaction mixture was quenched with aqueous NH4Cl and extracted with ethyl acetate. The organic layer was washed with brine, dried over sodium sulfate and concentrated in vacuo. The residue was purified over 25+S Biotage silica column (eluted with 0-30% ethyl acetate in hexane) to yield 110 mg (39%) of the title compound. 1H NMR (400 MHz, CDCl3) δ ppm 1.0 (m, 6H) 1.6 (m, 3H) 1.8 (m, 1H) 1.9 (d, J=12.4 Hz, 1H) 2.2 (s, 1H) 4.2 (s, 3H) 4.6 (d, J=7.5 Hz, 1H) 4.8 (m, 4H) 7.3 (s, 1H) 7.5 (m, 2H) 7.6 (s, 2H) 7.8 (s, 1H)).
