Reaktionsschritte
To a solution of 0.53 g of sodium hydride in 200 ml of DMF was added 2.2 g of 2-[(1,1'-biphenyl)-4-yl]ethanol, and the mixture was stirred at room temperature for one hour. Then 1.8 g of 4-chloroquinazoline in 20 ml of DMF were added, and the mixture was stirred at room temperature for another three hours. The mixture was then poured into a mixture of ice in water. The solid phase was collected and washed with water. TLC showed two spots. The product was purified using HPLC (silica gel, CH2Cl2) giving 1.1 g of the title product. Yield: 30.6%. M.P. 72°-74° C.
