| Abstract: | We describe here a rapid process for the preparation of new 9-chloromethyl-12-aryl-10,12-dihydrobenzo5,6]chromeno2,3-d]pyrimidin-11-ones 5a-d and 10-chloromethyl-7-aryl-7,9-dihydrobenzo7,8]chromeno2,3-d]pyrimidin-8-ones 6a-d by two different methods utilizing microwave irradiation. This methodology provides better yields (72%-80%) and high purity of the title compounds. |
