Reaction Steps

A solution of 33.5 g (0.107 mole) of 6-ethyl-5-[4-(phenylmethyl)-1-piperazinyl]-2,4-pyrimidinediamine in 400 ml of acetic acid was hydrogenated over 2 g of 20% palladium on charcoal under 3.5 atmospheres of hydrogen for 23 hours and filtered. The filtrate was concentrated in vacuo to dryness. The solid residue was poured into one liter of 2N sodium hydroxide solution. The solid was collected and washed with 500 ml of water. Recrystallization from acetonitrile and drying in vacuo at 59° C. for 16 hours gave 19.0 g of the product as a white solid; mp 204°-207° C.
