실험 절차

Following the same reaction and purification procedure, the amine 1 (100 mg, 0.42 mmol) was treated with sodium hydride 60% dispersion in mineral oil (25 mg, 0.62 mmol) and bromocyclobutane (56 mg, 0.42 mmol) to provide N-cyclobutyl-6-(3-fluorophenyl)pyrido[3,2-d]pyrimidin-4-amine 27 and N-(cyclopropylmethyl)-6-(3-fluorophenyl)pyrido[3,2-d]pyrimidin-4-amine 28. LC/MS (ESI+): m/z 295 (M+H). 1H NMR (400 MHz, DMSO) δ 8.80 (t, J=6.1 Hz, 1H), 8.48 (d, J=7.2 Hz, 2H), 8.39 (d, J=10.9 Hz, 1H), 8.22 (d, J=7.9 Hz, 1H), 8.15 (d, J=8.8 Hz, 1H), 7.60 (dd, J=14.3, 7.9 Hz, 1H), 7.34 (td, J=8.5, 2.4 Hz, 1H), 3.50 (t, J=6.5 Hz, 2H), 1.27 (dd, J=13.4, 6.1 Hz, 1H), 0.52-0.42 (m, 2H), 0.42-0.31 (m, 2H).
