Sodium Hydroxide → 2-(Aminomethyl)-1-(4-chlorobenzyl)pyrrolidine

Participants

Reaction Steps

500 ml of anhydrous tetrahydrofurane and 23.4 g (0.615 mol) of the double hydride of lithium and aluminium are introduced into a reactor equipped with a mechanical stirrer, and a solution of 27.3 g (0.108 mol) of 1-p-chlorobenzyl-2-nitromethylene-pyrrolidine in 1,000 ml of tetrahydrofurane is then added slowly. The reaction mixture is heated at the reflux temperature for 12 hours and then cooled, and 53 ml of water are added dropwise, followed by 53 ml of 20% strength sodium hydroxide solution and finally 53 ml of water. The precipitate is filtered off and extracted with 500 ml of ether. The ether solution is combined with the filtrate and dried over magnesium sulphate, the solvents are evaporated and the residue is distilled under reduced pressure. 19.5 g (yield: 80.2%) of 2-aminomethyl-1-p-chlorobenzyl-pyrrolidine distilling at 118°-120° under a pressure of 0.06 mm of mercury are obtained.
