実験手順

To a solution of 1-benzyl-piperidin-3-one hydrochloride salt (2.02 g, 8.95 mmol), aniline (1.67 ml, 17.89 mmol) in MeOH (20 ml) at room temperature was added NaCNBH3 (1.8 g, 28.64 mmol) in several portions. The mixture was stirred over night. The mixture was taken up in 50 ml of water, the pH was increased to 12 with 2N KOH and extracted with CH2Cl2 (3×50 ml). Standard work-up of the organic solution provided 164 as a dried residue which was used in the next step without further purification. LRMS (calculated for C18H22N2) 266, found 266.
