Reaction Steps

Into a 500-mL round-bottom flask purged and maintained with an inert atmosphere of nitrogen, was placed 2-[4-(aminomethyl)phenyl]quinazoline-4-carboxylic acid (2.6 g, 9.31 mmol, 1.00 equiv), oxolane (200 mL) and acetyl acetate (20 mL). The resulting solution was stirred for 3 h at 25° C. The resulting mixture was concentrated under vacuum. The residue was applied onto a silica gel column with dichloromethane/methanol (20:1-5:1). This resulted in 500 mg (17%) of 2-[4-(acetamidomethyl)phenyl]quinazoline-4-carboxylic acid as a light yellow solid. MS (ESI) m/z 322 ([M+H]+).
