Procedure
In 40 ml of tetrahydrofuran was suspended 4.61 g of potassium t-butoxide, to which 4.44 g of (2-fluorophenyl)acetonitrile was added under ice cooling. Then, a solution of 5.00 g of 4-chloro-6-(2-butynyloxy)pyrimidine in 20 ml of tetrahydrofuran was added at 0° C., followed by stirring at room temperature for 4 hours. The reaction mixture was then poured into a saturated aqueous ammonium chloride solution and extracted three times with chloroform. The chloroform layers were combined and washed with a saturated aqueous sodium chloride solution. The organic layer was dried over anhydrous magnesium sulfate and then concentrated. The residue was subjected to silica gel column chromatography to give 6.40 g of 4-α-cyano-2-fluorobenzyl)-6-(2-butynyloxy)pyrimidine (the present compound (145)).
