実験手順

1-ethyl-3-(4-(4-morpholino-5,6,7,8-tetrahydropyrido[3,4-d]pyrimidin-2-yl) phenyl)urea (0.0867 g, 0.227 mmol) in dry N,N-Dimethylformamide (1.00 mL, 12.9 mmol) at 0° C. was added N,N-Diisopropylethylamine (0.1190 mL, 0.6832 mmol) followed by Isobutyl chloroformate (0.0442 mL, 0.341 mmol). The reaction mixture was allowed to warm slowly to room temperature and stirred overnight. The reaction mixture was concentrated and purified by HPLC. 1H NMR (400 MHz, DMSO) δ 8.67 (s, 1H), 8.18 (d, J=8.8, 2H), 7.48 (d, J=8.8, 2H), 6.18 (t, J=5.6, 1H), 4.52 (s, 2H), 3.86 (d, J=6.5, 2H), 3.77-3.68 (m, 4 H), 3.58 (s, 2H), 3.47 (d, J=4.3, 4H), 3.17-3.06 (m, 2H), 2.73-2.62 (m, 2H), 1.92 (dp, J=13.2, 6.6, 1H), 1.06 (t, J=7.2, 3H), 0.93 (d, J=6.7, 6H).
