To a mixture of N-(2-(cyclohexyl(methoxy)methyl)-5-(trifluoromethyl)benzyl)-N-(3,5-bis(trifluoromethyl)benzyl)-2H-tetrazol-5-amine (40.4 mg, 0.068 mmol) and (2-bromoethoxy)(tert-butyl)dimethylsilane (25 mg, 22 μL, 0.10 mmol) in 2-MeTHF/DMF was added sodium carbonate (29.1 mg, 0.275 mmol). The slurry was stirred at 60° C. overnight. The reaction was diluted and filtered. The filtrate was concentrated and the residue was purified by chromatography over 12+S Biotage silica column (eluted with 0-20% ethyl acetate in heptane) to afford the title compound (39.3 mg, 77%). 1H NMR (400 MHz, CDCl3) δ ppm 0.08 (s, 6H) 0.80 (s, 9H) 0.92-1.12 (m, 5H) 1.15-1.21 (m, 1H) 1.42-1.52 (m, 1H) 1.57-1.62 (m, 2H) 1.68-1.72 (m, J=2.90 Hz, 1H) 1.89 (d, J=12.44 Hz, 1H) 3.03 (s, 3H) 4.05-4.09 (m, 3H) 4.54 (t, J=5.60 Hz, 2H) 4.64-4.76 (m, 3H) 4.89 (d, J=16.17 Hz, 1H) 7.35 (s, 1H) 7.47 (d, J=7.88 Hz, 1H) 7.54 (d, J=9.12 Hz, 1H) 7.65 (s, 2H) 7.75 (s, 1H).
