Participants

Reaction Steps

The reaction mixture was cooled and diluted with dichloromethane (30 ml), washed with water, brine and dried (MgSO4). The solvents were removed in vacuo to give a residue which was purified by silica flash chromatography to give 4-[benzyl-(2-methoxy-ethyl)-amino]-piperidine-1-carboxylic acid tert-butyl ester as a white solid (484 mg). 4-[Benzyl-(2-methoxy-ethyl)-amino]-piperidine-1-carboxylic acid tert-butyl ester (442 mg), and 2-chloro-4-morpholin-4-yl-thieno[3,2-d]pyrimidine-6-carbaldehyde (300 mg) were treated under standard reductive amination conditions to give benzyl-[1-(2-chloro-4-morpholin-4-yl-thieno[3,2-d]pyrimidine-6-ylmethyl)-piperidin-4-yl]-(2-methoxy-ethyl)-amine (379 mg), as an oil which crystallized on standing.
