Versuchsvorschrift
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).
