Методика

A suspension of the product of Example 1 (100 mg) in a 33% w/v solution of methylamine in ethanol (3 ml) was stirred for 18 hours. The solid formed, after filtration and washing with a little ethyl acetate, gave the title compound, 65 mg: m.p. 169°-171° C.; NMR (d6DMSO) δ 8.14 (2H, d), 8.06 (1H, bq), 8.00 (2H, d), 7.05 (2H, d), 6.80 (2H, d), 4.56 (2H, s), 3.82 (2H, s), 3.30 (4H, t), 2.66 (3H, d), 2.61 (4H, t); m/e 369 (M+H)+ ; calculated for C20H24N4O3 : C, 65.2; H, 6.6; N, 15.2. found: C, 65.0; H, 6.8; N, 15.1%.
