Reaction Steps

Sodium hydride (115 mg) was added to a solution of 2,6-dimethyl-3-hydroxymethyl-4-[(2'-(2-triphenylmethyl-2H-tetrazol-5-yl)biphenyl-4-yl)methoxy]pyridine (1.0 g) in DMF (30 ml) and the mixture was stirred for 10 minutes. Iodomethane (0.3 ml) was added and the mixture was stirred for 18 hours. Water (100 ml) was added and the mixture was extracted with ethyl acetate (2×50 ml). The combined extracts were washed with saturated sodium chloride solution (50 ml) and then dried (MgSO4). The solvent was removed by evaporation and the residue was purified by flash chromatography, eluting with a mixture of methanol and dichloromethane on a gradient from 1:50 v/v to 1:20 v/v, to give 2,6-dimethyl-3-methoxymethyl-4-[(2'-(2-triphenylmethyl-2H-tetrazol-5-yl)biphenyl-4-yl)methoxy]pyridine (A) (0.74 g), m.p. 132°-135° C.; NMR (d6 -DMSO/d4 -acetic acid): 2.55(s,6H), 3.2(s,3H), 4.45(s,2H), 5.25(s,2H), 6.8-7.9 (complex m,24H).
