Procedure

To a solution of 0.70 g of 2-butyl-6-[(trimethylsilyl)ethynyl]-4(1H)-quinazolinone in 20 ml of methanol and 20 ml of tetrahydrofuran is added 10.0 ml of 1.0N sodium hydroxide solution. The reaction is stirred at room temperature for 2 hours and then diluted with 5% hydrochloric acid solution until the pH is 2. The resulting tan precipitate is collected filtration and dried in vacuo to yield 0.50 g of the desired product.
