실험 절차

To a solution of 0.25 g of 2-butyl-1,4-dihydro-4-oxo-6-quinazolinecarboxaldehyde in 10 ml of dry tetrahydrofuran, cooled to a0° C., is added 1.63 ml of 2.0M ethyl magnesium bromide in tetrahydrofuran. The reaction mixture is stirred for 30 minutes at 0° C. and quenched with 20 ml of saturated ammonium chloride solution and 20 ml of water. The reaction mixture is extracted with 9:1 chloroform-methanol, dried over magnesium sulfate, filtered and evaporated in vacuo to give 0.26 g of the desired product.
