Reaction Steps

Ethyl formate (Acros) (11 mL) was added to a solution of 2-amino-5-(4-chlorophenoxy)-4-(piperazino)pyrimidine (0.433 g, 1.41 mmoles) in methanol, and after 16 hours the solution was spin evaporated in vacuo to give a colorless syrup. The syrup was triturated under hexanes containing 1% ethyl acetate to give a solid that was collected and recrystallized from ethyl acetate to give 0.250 g (53% yield) of 2-amino-5-(4-chlorophenoxy)-4-(4-formylpiperazino)pyrimidine as white crystals, mp 159-161° C.
