Reaction Steps

To a stirred mixture of 6-bromo-1-(2-chlorophenyl)-3,4-dihydroquinazolin-2(1H)-one (0.1993 g, 0.5903 mmol), N-cyclopropyl-4-methyl-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzamide (0.2134 g, 0.7084 mmol) and Pd(PPh3)4 (0.03411 g, 0.02952 mmol) was added 1,2-dimethoxyethane (5.000 ml) followed by 2N Na2CO3(aq) (0.7379 ml, 1.476 mmol) under nitrogen. The mixture was heated to reflux for 24. After cooling, the mixture was filtered through a short path of Celite and the filter cake was washed with EtOAc (3×10 mL). The combined organic layers were concentrated to give a crude product, which was purified using flash column chromatography (50% EtOAc in hexanes to 100% EtOAc) to afford 3-(1-(2-chlorophenyl)-2-oxo-1,2,3,4-tetrahydroquinazolin-6-yl)-N-cyclopropyl-4-methylbenzamide as a white solid. MS m/e 432 (M+H)+.
