Cyclopropanemethanamine → [1-(2-Chloro-4-morpholin-4-yl-thieno[3,2-d]pyrimidin-6-ylmethyl)-piperidin-4-yl]-cyclopropylmethyl-amine

Participants

Reaction Steps

To a solution of 1-(2-chloro-4-morpholin-4-yl-thieno[3,2-d]pyrimidin-6-ylmethyl)-piperidin-4-one (0.2 g, 0.545 mmol) in 1,2-dichloroethane (3 mL) were added cyclopropanemethylamine (71 μL, 0.812 mmol) and sodium triacetoxyborohydride (0.15 g, 0.71 mmol). The resulting suspension was stirred at RT for 17 h, then diluted with water and DCM. The aqueous layer was separated and extracted with DCM. The combined organic layers were dried (Na2SO4), then concentrated in vacuo to give the title compound as an off-white solid (0.10 g, 44%).
