Hydrochloric Acid → 3-(4,5-Dimethyl-1,2,3-triazol-1-yl)pyrrolidine hydrochloride

Participants

Reaction Steps

10% Pd/C (0.5 g) was added to a solution of 0.86 g of N-benzyl-3-(4 , 5-dimethyl-1,2,3-triazol-1-yl) pyrrolidine in 50 ml of methanol, and 2 ml of 1N hydrochloric acid. The suspension was then hydrogenated at 50 psi pressure overnight. The Pd/C was removed by filtration through celite and the supernatant was evaporated to dryness and crystallized from methanol-ether to yield 0.5 g of the desired product. 1H NMR (D2O) δ: 5.75-5.6 (m, 1H), 4.14-3.9 (m, 2H), 3.8-3.6 (m, 2H), 2.86-2.4 (m, 8H, two singlets at 2.49 and 2.4).
