1-ethylpiperidin-3-one

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: Following the procedure of Example 13 and using 1-benzyl-4-chloro-1H-imidazo[4,5-c]pyridine (0.60 g, 2.5 mmol) and (0.36 g, 2.8 mmol) of N-ethyl-3-piperidone gave the free base of the title compound which was purified by flash chromatography on silica gel eluting with EtOAc to give, after preparation of the salt, the dihydrochloride, 0.59 hydrate as an amorphous solid, 0.30 g (26%):

実験手順: A suspension of 0.25 g. of platinum dioxide in 20 ml. of methanol was shaken under 30 p.s.i. of hydrogen for one hour. To this activated catalyst was added a solution of 7.9 g. (48 mmoles) of 1-ethyl-3-piperidone and 3.1 g. (100 mmoles) of methylamine in 40 ml. of methnol. This mixture was shaken under about 50 p.s.i. of hydrogen for 1.5 hours, then filtered. The solvent was distilled off the filtrate at atmospheric pressure. The residue was then distilled at reduced pressure to give 1-ethyl-3-methylaminopiperidine, b.p. 88°-90.5° C. at 28 mm. A suspension of 0.25 g To this activated catalyst was added a solution of 7.9 g filtered The solvent was distilled off the filtrate at atmospheric pressure The residue was then distilled at reduced pressure
