Procedure

A mixture of 1.0 g of 2-butyl-7-fluoro-6-[(trimethylsilyl)ethynyl]-4(1H)-quinazolinone, 20 ml of 1N sodium hydroxide and 25 ml of methyl alcohol is heated at 60° C. for 5 hours then evaporated in vacuo. The residue is dissolved in 100 ml of water and acidified. The resulting solid is collected and dried to afford 700 mg of the desired product as a yellow solid, m.p. 218° C.
