Reaction Steps

A solution of intermediate 58, 4-fluoro-2-(2-methyl-2H-tetrazol-5-yl)-benzonitrile, (330 mg, 1.62 mmol) in ethanol (15 mL) was mixed with 6N HCl (1 mL) and 10% Pd—C (200 mg) under nitrogen. The mixture was then stirred under hydrogen (1 atm) for 3 hrs. After removing the catalyst, the filtrate was concentrated in vacuo to provide 360 mg (Yield 91%) of the title compound as an off-white solid; 1H NMR (500 MHz, DMSO-D6) δ ppm: 4.42 (2 H, d, J=2.75 Hz) 4.49 (3 H, s) 7.48-7.56 (1 H, m) 7.78 (1 H, dd, J=8.7, 5.7 Hz) 7.86 (1 H, dd, J=9.8, 2.8 Hz) 8.45 (3 H, s); LC/MS m/z 208.
