Reaction Steps

A solution of 2-(4-bromophenyl)-5,7-dimethoxyquinazolin-4(3H)-one (8) (3.23 mmol), K2CO3 (9.69 mmol), PdCl2(dppf) (0.32 mmol) and tert-butyl 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-5,6-dihydropyridine-1(2H)-carboxylate (9) (3.23 mmol) in DMF (50 mL) was heated to 110° C. overnight. The resulting solution was concentrated in vacuo and the material was purified by flash chromatography on silica gel to give tert-butyl 4-(4-(5,7-dimethoxy-4-oxo-3,4-dihydroquinazolin-2-yl)phenyl)-5,6-dihydropyridine-1(2H)-carboxylate (10).
