반응 단계
30 mL (0.162 Mol) 1-benzylpiperidone (L) and 16.1 mL (0.185 Mol) morpholine (M) are dissolved in 407 mL tetrahydrofuran at ambient temperature. While cooling, 1.0 g (5 mmol) of p-toluenesulphonic acid and 14.6 mL glacial acetic acid are added, whereupon a jelly-like precipitate is formed. 52.19 g (0.246 Mol) sodium triacetoxyborohydride are added while cooling with ice, during which time the reaction temperature rises to 30° C. After 4 hours at 20° C., 90 mL water are added dropwise. After another 30 minutes, 280 mL of 17% potassium carbonate solution are added. The mixture is stirred intensively, while gas is observed to be given off. After separation of the phases the organic phase is dried and evaporated down. Yield: 33.0 g (78% of theory)
