In ethanol; butan-1-ol; | B. Title compound A solution of 11.4 g (0.1 mol) of 3-amino-1-ethylpyrrolidine and 14.4 g (0.08 mol) of <strong>[58533-15-6]2-chloro-1-ethylbenzimidazole</strong> in 40 mL of ethanol was heated at reflux for 72 h. A mass spectal analysis showed the reaction to be about 25% complete. The solution was concentrated on the rotary evaporator (60 C./30 mm) and the residue was dissolved in 50 mL of n-butanol. The solution was heated to reflux for 24 h and partitioned between CHCl3 and dilute NaOH. The CHCl3 solution was dried (Na2 SO4) and concentrated. The residue was chromatographed on the Waters Associates preparative HPLC (silica gel/isopropyl alcohol). The purified material was isolated as the fumarate salt by the following procedure. The collected material (6 g, 0.023 mol) was treated with 2.7 g, 0.023 mol) of fumaric acid. The resulting crystals weighed 3.5 g and melted at 189-191 C. Analysis: Calculated for C15 H22 N4.2C4 H4 O4: C, 56.32; H, 6.16; N, 11.42. Found: C, 56.22; H, 6.24; N, 11.48. |

92.7% | To a solution of 2-chloro-1H- benzo[d]imidazole (1 g, 6.553 mmol) in DMF (50 mL) was added NaH (340.8 mg, 8.519 mmol) at 0 oC. After 15 minutes, bromoethane (1.33 g, 8.519 mmol) was added to the reaction mixture at 0 oC. The reaction mixture was stirred at r.t. for 2 hours. TLC (Petroleum ether/EtOAc = 5/1; silica gel plate) showed complete consumption of the starting material after this time. The mixture was quenched by water at 0 oC. The reaction mixture was extracted with EtOAc (50 mL x 2), washed with brine and the combined organic layers were dried over anhydrous Na2SO4 and concentrated under reduced pressure. The residue was purified via column chromatography (Petroleum ether/EtOAc) to give the title compound (1.1 g, 92.7% yield) as a white solid.
