实验过程

247 mg of sodium are treated at room temperature with 10 ml of methanol. After 15 minutes the solution obtained is treated at room temperature with 1.58 g of 4-amidinobenzamide hydrochloride. A white suspension forms and this is treated dropwise at room temperature within 10 minutes with a solution of 1.42 g of 2-(4-cyanophenyl)-3-methoxyacrolein in 50 ml of methanol. The reaction mixture is stirred at room temperature for a further 2 hours and then suction filtered. The residue is washed with water, tetrahydrofuran and diethyl ether and dried in a high vacuum. 4-[5-(4-Cyanophenyl)-2-pyrimidinyl]benzamide is obtained.
