    • General procedure: A mixture of N-tosylaziridine (1 mmol, nitrile (10 mmol, and PMA-SiO2 (10 mol, was stirred at ambient temperature for the appropriate time (Table 1, After completion of the reaction as indicated by TLC, the reaction mixture was filtered and washed with dichloromethane (3 × 10 mL, The combined organic layers were dried over anhydrous Na2SO4, concentrated in vacuo and purified by column chromatography on silica gel (Merck, 100-200 mesh, ethyl acetate-hexane, 2:8) to afford pure imidazoline. The products were characterized by NMR, IR, and mass spectrometry and also by comparison with authentic samples.8,9 2-Ethyl-4,5-dihydro-4-(4-methoxyphenyl)-1-tosyl-1H-imidazole (3f) Viscous liquid: IR (neat, v(max) 3283, 2925, 2854, 1646, 1513, 1328, 1158, 1092, 814, 663cm-1. 1HNMR (300 MHz, CDCl 3, δ 7.77-6.76 (m, 8H, 4.93 dd, J, 8.0, 10.2 Hz, 1H
