Participants

Reaction Steps

Sodium hydride (60% dispersion in mineral oil, 62 mg) was added in a solution of 2-ethyl-6-(2-hydroxyethoxy)-4-[(2'-(2-triphenylmethyl-2H-tetrazol-5-yl)biphenyl-4-yl)methoxy]-1,5-naphthyridine (1.0 g) in THF (10 ml). The mixture was stirred until evolution of hydrogen had ceased and then methyl iodide (0.09 ml) was added. The solution was left to stand for 72 hours and then water (30 ml) was added. The mixture was extracted with ether (2×20 ml) and the combined extracts were dried (MgSO4). Volatile material was removed by evaporation and the residue was triturated with hexane to give 2-ethyl-6-(2-methoxyethoxy)-4-[(2'-(2-triphenylmethyl-2H-tetrazol-5-yl)biphenyl-4-yl)methoxy]-1,5-naphthyridine (A) (0.86 g), as a foam; NMR (d6 -DMSO): 1.3(t, 3H), 2.8(q, 2H), 3.25(s, 3H), 3.6-3.7(m, 2H), 4.45-4.55(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).
