Procedure
A mixture of tert-butylamine (1.1 mL, 10.43 mmol) and 8-bromo-2-chloro-3-ethylquinazolin-4(3H)-one (100 mg, 0.348 mmol, 481c) was sealed and set stirring for 3 h at 80° C. The reaction was cooled to RT, diluted with water, and extracted with DCM. The combined organics were dried over Na2SO4, filtered, and concentrated under reduced pressure giving a pale yellow solid. The material was taken up DCM, adsorbed onto silica, and purified on 4 g SiO2 (eluent: 0-100% EtOAc/hexanes over 20 min, RediSep Gold). The product containing fractions were combined and concentrated under reduced pressure to a colorless residue (52 mg, 46%). m/z (ESI, +ve) 323.9 (M+H)+.
