Reaction Steps

4-Chloro-5-phenoxy pyrimidine is dissolved in absolute ethanol saturated with ammonia and added ammonium chloride, and heated in a stainless steel pressure bomb at about 160°C. for approximately 6 hours. The ethanol is removed under vacuum, and the oily residue taken up in ether. Concentration of the ether extract gives 4-amino-5-phenoxy pyrimidine as a yellow solid which is taken up in hot ethyl acetate, treated with activated charcoal, filtered and cooled to provide white crystals.
