Trifluoroacetic acid → (3RS,4RS)-5-(3-benzyloxy-propoxy)-2-[3-(naphthalen-2-ylmethoxy)-piperidin-4-yl]-pyrimidine trifluoroacetate

Participants

Reaction Steps

A solution of 40 mg (0.07 mmol) of tert-butyl (3RS,4RS)-4-[5-(3-benzyloxy-propoxy)-pyrimidin-2-yl]-3-(naphthalen-2-ylmethoxy)-piperidine-1-carboxylate and 0.1 ml of trifluoroacetic acid in 1 ml of methylene chloride was stirred at room temperature for 2 hours. Thereafter, the solution was evaporated and the residue was taken up in 1 ml of ethyl acetate and crystallized by the addition of hexane. There were obtained 25 mg (60% of theory) of (3RS,4RS)-5-(3-benzyloxy-propoxy)-2-[3-(naphthalen-2-ylmethoxy)-piperidin-4-yl]-pyrimidine trifluoroacetate in the form of colourless crystals; MS: 484 (M+H)+.
