Versuchsvorschrift

A stirring solution of (E)-N-(2-isobutoxy-3-methoxybenzyl)-N-methyl-3-(2-oxo-2,3,4,5-tetrahydro-1H-pyrido[2,3-e][1,4]diazepin-7-yl)acrylamide (0.108 g, 0.246 mmol) in CH2Cl2 (3 mL) under N2 was treated with HCl (0.12 mL of a 2.0 M solution in diethyl ether, 24 mmol). After stirring for 18 h, the resulting solid was collected by filtration and washed with Et2O (100 mL) and dried. The solid was dissolved in CH2Cl2 (2 mL) and layered with hexanes (5 mL). The resulting solids were collected by filtration, washed with Et2O (50 mL) and dried to yield the target compound (0.052 g, 45%) as a tan solid and as a mixture of amide rotamers: 1H NMR (300 MHz, DMSO-d6) δ 11.09-11.07 (m, 1H), 10.03 (br s, 2H), 8.77-8.71 (m, 1H), 8.31-8.24 (m, 1H), 7.62-7.54 (m, 1H), 7.38-7.31 (m, 1H), 7.05-6.59 (m, 2H), 6.68-6.59 (m, 1H), 4.81-4.65 (m, 2H), 4.27-4.23 (m, 2H), 3.85-3.82 (m, 2H), 3.79 (s, 3H), 3.72-3.68 (m, 2H), 3.12-2.88 (m, 3H), 2.06-1.97 (m, 1H), 1.00-0.98 (m, 6H); MS (ESI) m/e 439 (M+H)+.
