Reaction Steps

p-Cyanobenzylamine (13.2 g), water (54 g), and toluene (20 g) were mixed, and the mixture was stirred with cooling with ice. Concentrated sulfuric acid (14.7 g) was added to the mixture. Subsequently, a 20 wt % aqueous solution (44.9 g) of sodium nitrite was added dropwise to the mixture over one hour. The mixture was stirred at the same temperature for four hours. For the subsequent process, the procedure of Example 1 was repeated, to thereby obtain 6.8 g of p-cyanobenzyl alcohol (yield 51%). The purity of the product was 98%.
