To a solution of 1.1 g of sodium hydride in 50 ml of DMF, 4.0 g of 2-[4-(t-butyl)phenyl]ethanol was added, and the mixture was stirred at room temperature for one hour. Then 3.6 g of 4-chloroquinazoline in 20 ml of DMF were added, and the mixture was stirred at room temperature overnight. The mixture was then poured into a mixture of ice in water. The product was extracted into CH2Cl2, and the resulting solution was concentrated to dryness. TLC showed one major spot and five minor spots. The product was purified by HPLC (silica gel, CH2Cl2). The fractions containing the major product were collected and concentrated, giving 1.9 g of the title product. Yield: 28.4%. M.P. 70°-71° C.
