実験手順

To a stirring solution of 1-Methyl-1H-imidazole-4-carboxylic acid (3-aza-bicyclo[3.1.0]hex-6-ylmethyl)-(3-trifluoromethoxy-benzyl)-amide Hydrochloride prepared above (0.8 gm, 1.9 mmol) in 18.5 mL of DCE at room temperature was added Cyclopropanecarbaldehyde (0.1 mL, 1.6 mmol) and NaHB(OAc)3 (0.8 gm, 3.7 mmol). The reaction stirred at room temperature for 16 hours, was quenched by the addition of saturated NaHCO3, and extracted with CH2Cl2. The combined organic layers were dried over anhydrous MgSO4, filtered and concentrated under reduced pressure to yield the crude material, which was purified via flash chromatography with 5-30% MeOH/CH2Cl2. The product containing fractions were collected and concentrated to yield 1-Methyl-1H-imidazole-4-carboxylic acid (3-cyclopropylmethyl-3-aza-bicyclo[3.1.0]hex-6-ylmethyl)-(3-trifluoromethoxy-benzyl)-amide 0.5 gm. 400 MHz 1H NMR (CDCl3) δ 7.5 (s, 1H), 7.3 (m, 2H) 7.2-7.0 (m, 3H), 5.5 (brs, 1H) 4.8 (brs, 1H), 4.0 (brs, 1H), 3.7 (s, 3H), 3.3 (brs, 1H), 3.0 (m, 2H), 2.2 (m, 4H), 1.5 (brs, 1H), 1.3 (m, 2H), 0.8 (m, 1H), 0.4 (m, 2H), 0.0 (m, 2H); MS (M+1) 449.3.
