Versuchsvorschrift

A 1M solution of tetrabutylammonium fluoride in tetrahydrofuran (THF) (67.8 ml) was added to a solution of compound E (32.1 g) in dry THF (400 ml), and the solution was left to stand for 1 hour. The solution was then diluted with ethyl acetate (400 ml), washed with water (400 ml) and dried (MgSO4). Volatile material was removed by evaporation, and the residue triturated with ether to give 2-ethyl-6-(2-hydroxyethoxy)-4-[(2'-(2-triphenylmethyl-2H-tetrazol-5-yl)biphenyl-4-yl)methoxy]-1,5-naphthyridine (A) (21.6 g), as a white solid, m.p. 170°-173° C.; NMR (d6 -DMSO): 1.3(t,3H), 2.85(q,2H), 3.75(q,2H), 4.45(t,2H), 4.85(t,1H), 5.35(s,2H), 6.8-6.9(m,7H), 7.1-7.7 (complex m,17H), 7.8(dd,1H), 8.15(d,1H).
