dc.titleSynthesis of Thieno[2,3-D]Pyrimidines from 4,6-Dichloropyrimidine-5-Carbaldehydesen
heal.abstractSeveral thieno[2,3-d]pyrimidines have been prepared by intramolecular cyclisation of 6-(substituted methylthio)-5-pyrimidinecarbaldehyde and carbonitrile intermediates derived from 6-chloropyrimidine-5-carbaldehydes and 5-carbonitriles and methyl thioglycolate or 5-formylpyrimidine-4-(3H)-thiones and appropriate alpha-halogeno compounds. Thienopyrimidines 18 and 5c were nitrated to the corresponding nitro compounds 23 and 24. Hydrolysis at position 4 of compound 18 also occurred during nitration. The ester 5g was hydrolysed in base to the acid 25.en
