Reaction Steps

Into a 500-mL round-bottom flask, was placed ethyl 2-[4-[(1,3-dioxo-2,3-dihydro-1H-isoindol-2-yl)methyl]phenyl]quinazoline-4-carboxylate (4 g, 9.14 mmol, 1.00 equiv), ethanol (40 mL) and 1N KOH (70 mL). The resulting solution was stirred for 24 h at 100° C. in an oil bath. The pH value of the solution was adjusted to 7 with acetic acid. The resulting mixture was concentrated under vacuum. This resulted in 2.6 g (crude) of 2-[4-(aminomethyl)phenyl]quinazoline-4-carboxylic acid as a white solid. MS (ESI) m/z 280 ([M+H]+).
