Preparation of Benzylamine:
Patent GB619827 (http://l2.espacenet.com/dips/viewer?PN=GB619827&CY=gb&LG=en&DB=EPD)
Example 1:
60g of benzyl chloride, 60 of urea and 40cc of water are refluxed for 5 hours, after which unreacted benzyl chloride is removed by steam distillation. The mixture is then allowed to cool and the crude benzyl urea is removed by filtration. The benzyl urea may be recrystallized from water. Benzyl urea thus obtained has; MP: 142-143°C, Yield: 42g
42g of benzyl urea and 50g of caustic soda are heated together to an internal temperature of the order of 250°C. and the crude benzylamine formed is distilled. The crude benzylamine can be purified by aspirating with nitrogen to remove ammonia and redistilling. Yield: 30g
