4-Toluenesulfonyl chloride → HCID 19803495, compound

Participants

Reaction Steps

1.3 g (0.005 mol) of N-[2-(3,4-dimethoxy-phenyl)-ethyl]-3-hydroxymethyl-pyrrolidine are dissolved in 10 ml of pyridine, 1.05 g (0 0055 mol) of p-toluenesulphonic acid chloride are added and the mixture is stirred for 6 hours at ambient temperature. The excess pyridine is then distilled off in vacuo, the residue obtained is dissolved in methylene chloride and the organic phase is extracted with ice water. After the organic phase has been dried over magnesium sulphate it is concentrated by evaporation in vacuo. Yield: 1.4 g (66.7% of theory), Rf value: 0.40 (aluminium oxide, neutral, eluant: 2% ethanol in methylene chloride).
