Procedure

Piperidine (1 mL) was added to compound 178 (0.161 g, 0.5 mmol) and the reaction mixture was stirred for 19.5 h. The reaction mixture was then concentrated under reduced pressure to give a yellow gum. Trituration with 1:4 EtOAc:hexanes gave a small amount of compound 179 (0.041 g). Flash chromatography (1:4 EtOAc:hexanes) of the filtrate gave only a partially separable mixture of the expected products, the acetoxyquinazolinone compound 179 and the hydroxyquinazolinone (total mass 0.122 g). ESI-MS m/z=408 (MH+). The reaction described above and compound 179 are shown below.
