合成路线1
该中间体在本合成路线中的序号：(IV)ABPP is a phenylpyrimidinone and as such is prepared in high yield by condensation of guanidine with ethyl benzoylacetate. Ethyl benzoylacetate is commercially available and can also be prepared in high yield by condensation of dilithiomonoethylmalonate at 78 C with benzoyl chloride. Reaction of the resultant beta-ketoester with guanidine in refluxing ethanol affords its pyrimidinone in high yield. ABPP can be prepared from this pyrimidinone by bromination in acetic acid at room temperature. Similarly, iodine can be introduced at this step to afford the iodo analogue, AIPP. The overall yield of these pyrimidinones from monoethylmalonate is generally) 50%.
