3-amino-N,N-dimethylpropane-1-sulfonamide → 3-[(2-Chloro-4-morpholin-4-yl-thieno[3,2-d]pyrimidin-6-ylmethyl)-amino]-propane-1-sulfonic acid dimethylamide

Participants

Reaction Steps

To a solution of 2-chloro-4-morpholin-4-yl-thieno[3,2-d]pyrimidine-6-carbaldehyde (280 mg) in methanol (10 mL) was added 3-amino-propane-1-sulfonic acid dimethylamide (284 mg) and the reaction stirred at room temperature for 16 h. The solvent was reduced in vacuo and the residue redissolved in ethanol (50 mL). Palladium on carbon (20 mg) was added and the reaction stirred at room temperature under a hydrogen balloon for 48 h. The reaction was then filtered through Celite and the filtrate reduced in vacuo to give 3-[(2-chloro-4-morpholin-4-yl-thieno[3,2-d]pyrimidin-6-ylmethyl)-amino]-propane-1-sulfonic acid dimethylamide as a yellow solid.
