MS (ESI) [M + H]+ for C16H20N3O4+: determined 318.1, found 318.1. 1-(2-Oxo-2-(piperidin-1-yl)ethyl)-3-(quinazolin-7-yl)urea (7) To a remedy of quinazolin-7-amine (73 mg, 0.5 mmol, 1.0 equiv) in DMF (1.5 mL) was added CDI (90 mg, 0.55 mmol, 1.1 equiv), as well as the resulting mixture was stirred for 8 h at rt. 2-Amino-1-piperidin-1-ylethanone hydrochloride sodium (134 mg, 0.75 mmol, 1.5 equiv) was then added accompanied by Hunigs base (131 L, 0.75 mmol, 1.5 equiv). After becoming stirred for 18 h at rt, the ensuing blend was diluted with drinking water (25 mL) and extracted with EtOAc (3 25 mL). Mixed organic layers had been dried out over sodium sulfate and focused under decreased pressure to provide crude product, that was after that purified by adobe flash column chromatography to yield desired compound (10 mg, 6%). 1H NMR (600 MHz, methanol-= 2.1 Hz, 1H), 8.00 (d, = 8.9 Hz, 1H), 7.71 (dd, = 8.9, 2.1 Hz, 1H), 4.14 (s, 2H), 3.58 (t, = 5.6 Hz, 2H), 3.47 (t, = 5.5 Hz, 2H), 1.75C1.53 (m, 6H). MS (ESI) [M + H]+ for C16H20N5O2+: determined 314.2, found 314.2. 1-(Isoquinolin-7-yl)-3-(2-oxo-2-(piperidin-1-yl)ethyl)urea (8).
