N-(2-(哌啶-4-基)乙基)甲磺酰胺

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 4-(2-Methanesulphonamidoethyl)pyridine (8.4 g.) in ethanol (85 ml.) was acidified to pH 2 with 2 N HCl and hydrogenated at room temperature and a pressure of 50 p.s.i. over a platinum oxide catalyst until hydrogen uptake ceased. The catalyst was then removed by filtration and the filtrate was taken to dryness in vacuo to give a white solid which was dissolved in the minimum volume of hot ethanol, filtered quickly, and left at room temperature overnight. The resultant white crystals were collected by filtration and dried to yield 4-(2-methanesulphonamidoethyl)piperidine:hydrochloride (8.3 g.), m.p. 165°-167° C. The catalyst was then removed by filtration to give a white solid which filtered quickly The resultant white crystals were collected by filtration dried
