Abstract: Objective To prepare 2-substitudephenoxy-5-benzyloxypyrimidines and 2-substitudephenoxy-5-hydroxypyrimidines which had not been reported. Methods The target compounds were prepared from 2-chlorine-5-hydroxypyrimidine through hydroxy protection, Williamsom reaction and reduction of benzyl group. Results The synthetic process provided a simple, easy diposal procedure and high overall yield. Fourteen new phenoxy pyrimidines compounds were prepared. Conclusions It was a new synthetic method which was easy to operate with moderate reaction conditions. -
