Reaction Steps

To a solution of N-(2-(methoxy(piperidin-4-yl)methyl)-5-(trifluoromethyl)benzyl)-N-(3,5-bis(trifluoromethyl)benzyl)-2-methyl-2H-tetrazol-5-amine (19.5 mg, 0.030 mmol) in methylene chloride (0.2 mL) at room temperature was added Hunig's base (7 mg, 10 μL, 0.06 mmol) followed by phosgene in toluene (20%, 25 μL, 0.048 mmol). The mixture was stirred at room temperature for 1 hour. Aqueous ammonia (0.2 mL) was added. The mixture was stirred at room temperature overnight. Solvent was removed in vacuo. The residue was purified by chromatography over 12+S Biotage silica column (eluted with 1-7% methanol in methylene chloride) to afford the title compound (13 mg, 62%). 1H NMR (400 MHz, CDCl3) δ ppm 1.15-1.21 (m, 1H) 1.23-1.37(m, 2H) 1.61-1.76(m, 3H) 1.88(d, J=12.45 Hz, 1H) 2.57-2.73 (m, 2H) 3.04 (s, 3H) 3.86-3.97 (m, 2H) 4.18 (d, J=7.05 Hz, 1H) 4.21 (s, 3H) 4.66-4.73 (m, 3H) 4.87 (d, J=16.18 Hz, 1H) 7.36 (s, 1H) 7.50 (d, J=7.88 Hz, 1H) 7.58 (d, J=8.30 Hz, 1H) 7.64 (s, 2H) 7.78 (s, 1H).
