Reaction of 2,4-dichlorothienopyrimidines and -quinazolines 1 with sodium borohydride gave the corresponding 2-chloro-3,4-dihydro derivatives 2.Some nucleophilic substitutions of 2b afforded 2-substituted derivatives 3b-7b and reaction of 2g,h with ethyl bromoacetate yielded selectively the corresponding 3-substituted compounds 8g,h which were derived to imidazoquinazolin-2-ones 9g,h.
