Reaction Steps

To a suspension of (6-Methoxy-quinazolin-4-yl)-[3-methyl-4-(piperidin-4-yloxy)-phenyl]-amine hydrochloride (108mg, 0.251 mmol) in N,N-dimethylformamide (1.0 mL) was added triethylamine (143 μL, 1.03 mmol) and the preformed acyl imidazolide (0.343 mmol). The acyl imidazolide is prepared by mixing CDI (56 mg, 0.343 mmol), DMF (1 mL) and cyclopropylacetic acid (34 mg, 0.343 mmol) and stirring for one hour at ambient temperature. After addition of the acyl imidzolide, the reaction was stirred at room temperature overnight. The reaction was then filtered through a 0.45 μm PTFE membrane filter and purified by preparatory HPLC. 71.4 mg of 2-Cyclopropyl-1-{4-[4-(6-methoxy-quinazolin-4-ylamino)-2-methyl-phenoxy]-piperidin-1-yl}-ethanone was isolated. 1H NMR (300 MHz DMSO d6), δ 9.505 (s, 1H), 8.435 (s, 1H) 7.904 (d, J=9.0, 2.7 Hz, 1H), 7.708 (d, J=9.0 Hz, 1H), 7.552 (dd, J=2.7 Hz, 1H), 7.576-7.511 (m, 2H), 7.480 (dd, J=9.0, 2.7 Hz, 1H), 7.062 (d, J=9.0 Hz, 1H), 4.647-4.600 (m, 1H), 3.951 (s, 3H), 3.951-3.730 (m, 1H), (m, 1H), 3.729-3.645 (m, 1H), 3.442-3.369 (m, 3H), 2.300 (d, J=6.9 Hz, 2H), 2.223 (s, 1H), 1.985-1.882 (m, 2H), 1.692-1.576 (m, 2H) 0.980 (m, 1H), 0.499-0.439 (m, 2H), 0.162-0.113 (m, 2H).
