78% | With ammonium hydroxide In methanol at 0 - 20℃; | Compound 44.1. 2-Cyclopropyl-lH-imidazole. Into a 25-mL round-bottom flask, was placed a solution of cyclopropanecarbaldehyde (500 mg, 7.13 mmol), oxaldehyde (455 mg, 7.84 mmol) in methanol (5 mL). The solution was cooled to 0 °C, then 25percent ammonium hydroxide (1 mL) was added drop-wise. The resulting solution was stirred for 3 h at 0 °C, then stirred at room temperature overnight. The resulting mixture was concentrated under reduced pressure and the residue was dissolved in brine (50 mL). The aqueous phase was extracted with ethyl acetate (3 x 10 mL) and the combined organic layers were dried (Na2S04), filtered, and concentrated under reduced pressure to yield 600 mg (78percent) of the title compound as a light brown solid. |
