Reaction Steps

To a stirred mixture of 4-chloro-8-isopropoxy-2-methyl-quinazoline (35) (0.58 mmol), phenylboronic acid (0.62 mmol), 2 N Na2CO3 (7.2 mL), EtOH (1.2 mL) and benzene (6 mL) was added, under a blanket of argon, Pd(PPh3)4 (20 mg). The mixture was stirred under reflux for 16 h, cooled, and concentrated. Subsequent column chromatography (ethyl acetate/hexane) provided 8-isopropoxy-2-methyl-4-phenyl-quinazoline (36) as a solid.
