Triethylamine → 2-Chloro-6-(7-methanesulfonyl-2,7-diaza-spiro[3.5]non-2-ylmethyl)-4-morpholin-4-yl-thieno[3,2-d]pyrimidine

Participants

Reaction Steps

To a solution of 2-chloro-6-(2,7-diaza-spiro[3.5]non-2-ylmethyl)-4-morpholin-4-yl-thieno[3,2-d]pyrimidine (71 mg, 0.18 mmol) in anhydrous DCM (3 mL) was added triethylamine (160 μL, 1.46 mmol) and a solution of methanesulfonyl chloride (17 μL, 0.22 mmol) in anhydrous DCM (0.5 mL). The resulting mixture was stirred at RT for 18 h, then diluted with DCM and brine. The organic layer was separated, dried (Na2SO4) and concentrated in vacuo. The resultant residue was purified by column chromatography to give the title compound as a yellow oil (55 mg, 65%).
