The reaction mixture was concentrated to oil from which the title compounds were isolated by column chromatography using silica gel and a mixture of CHCl3, hexane, MeOH (4:4:1) as eluant. N-benzyl-3-(5-phenyl-1,2,3-triazol-1-yl)pyrrolidine was obtained as oil. Yield: 1 g (22.17%). 1H NMR (CDCl3) δ: 2.32-2.51 (m, 2H), 2.88-3.13 (m, 2H), 3.80 (s, 2H), 5.00 (p, 1H), 7.20-7.53 (m, 10H), 7.67 (s, 1H). N-benzyl-3-(4-phenyl-1,2,3-triazol-1-yl)pyrrolidine, oil, yield 3.0 g. 1H NMR (CDCl3) δ: 2.05-2.22 (m, 1H), 2.30-2.69 (m, 2H), 2.75-3.25 (m, 3H), 5.20- 5.33 (m, 1H), 7.23-7.51 (m, 8H), 7.81-7.92 (m, 2H), 8.06 (s, 1H).
