Abstract
3-Amino-2-mercapto-3,5,6,7,8,9-hexahydro-4H-cyclohepta[4,5]thieno[2,3-d]pyrimidin-4-one (4) was prepared, and from this a series of 2-(arylaminomethyl)-7,8,9,10-tetrahydro-6H,11H-cyclohepta[4,5]thieno[2,3-d][1,3,4]thiadiazolo [3,2-a]pyrimidin-11-ones (6a–d) were synthesised through the corresponding 2-chloromethyl compound (5) with aromatic amines under microwave irradiation.
