実験手順
An ethanol solution of 39 (0.86 g, 2.42 mmol) was saturated with ammonia and stirred overnight at room temperature. The solvent was evaporated and the residue was purified by Flash™ (BIOTAGE, Inc) (90 g silica gel cartridge 40M, 6:1:0.1 chloroform/ethanol/concentrated ammonium hydroxide) to provide 40 (0.75 g, 87%) as a white solid. 1H NMR (300 MHz, DMSO-d6) δ 1.40 (m, 2H), 1.51 (m, 2H), 2.50 (m, 2H), 2.58 (m, 1H), 2.68 (m, 1H), 3.00 (m, 2H), 3.69 (m, 1H), 3.80 (m, 1H), 3.90 (m, 1H), 5.08 (s, 2H), 6.82 (d, 2H), 7.06 (d, 2H), 7.35 (br s, 5H).
