실험 절차

To a solution of 1.1 g of sodium hydride in 50 ml of DMF was added 3.4 g of 2-(4-chlorophenyl)ethanol, 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 overnight. The mixture was then poured into a mixture of ice in water. Solid was collected and recrystallized from pentane giving 0.149 g of the title product. Yield: 2.4%. M.P. 57°-58° C.
