Reaction Steps
To 2-chloro-7-methyl-4-morpholin-4-yl-6-piperazin-1-ylmethyl-thieno[3,2-d]pyrimidine (100 mg) in anhydrous DCM (2 ml) and triethylamine (1.5 equiv., 60 μl) at 0° C. was added cyclopropanesulfonyl chloride (1.1 equiv., 31 μl) and the reaction mixture was allowed to warm up to room temperature overnight. DCM/brine extraction and purification on silica gave 2-chloro-6-(4-cyclopropanesulfonyl-piperazin-1-ylmethyl)-7-methyl-4-morpholin-4-yl-thieno[3,2-d]pyrimidine (101 mg).
