Procedure

To 2-chloro-4-morpholin-4-yl-6-piperazin-1-ylmethyl-thieno[2,3-d]pyrimidine (150 mg) in anhydrous DCM (4 ml) and triethylamine (90 ul) was added 2-thiophenesulfonyl chloride (101 ul) at 0° C. The reaction mixture was allowed to warm up to room temperature over 4 hours. Aqueous work-up and purification on silica gave 2-chloro-4-morpholin-4-yl-6-[4-(thiophene-2-sulfonyl)-piperazin-1-ylmethyl]-thieno[2,3-d]pyrimidine (208 mg).
