Sodium hydride (0.1 mole) is added to benzyl alcohol (0.1 mole) in 100 ml. dry benzene and the mixture is refluxed one to two hours. The cooled solution is treated with 0.1 mole of 2-amino-3-morpholino-5-bromopyrazine in 100 ml. of benzene and the resulting mixture refluxed for 20-60 hours whereupon it is cooled, washed with water, dried and evaporated to give 2-amino-3-morpholino-5-benzyloxypyrazine.
