실험 절차

A saturated solution of hydrogen chloride in ethanol (0.1 ml) was added to a solution of compound B (600 mg) and morpholine (450 mg) in methanol (10 ml) containing 3A molecular sieves (1 g). Sodium cyanoborohydride (53 mg) was added and the mixture was stirred for 20 hours. Volatile material was removed by evaporation and the residue purified by flash chromatography, eluting with methanol/ethyl acetate (1:9 v/v). to give 2-ethyl-6-[2-(4-morpholino)ethoxy]-4-[(2'-(2-triphenylmethyl-2H-tetrazol-5-yl)biphenyl-4-yl)methoxy]-1,5-naphthyridine (A) (152 mg), m.p. 135°-137° C. (after trituration with hexane); NMR (d6 -DMSO): 1.3(t, 3H), 2.3-2.45(m, 4H), 2.6-2.8(m, 2H), 2.85(q, 2H), 3.4-3.55(m, 4H), 4.45-4.6(m, 2H), 5.4(s, 2H), 6.8-6.9(m, 6H), 7.1-7.7(complex m, 18H), 7.8(dd, 1H), 8.15(d, 1H).
