反応条件: temp:0.00; pressure:0.00; stir:

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To a solution of benzene-1,2-diamine (1.62 g, 15.0 mmol) and cyclopropanecarbaldehyde (1.05 g, 15.0 mmol) in MeOH (15 mL) at 0° C. was added NaCNBH3 (2.07 g, 33.0 mmol) and acetic acid (0.2 mL). The ice bath was removed and the resulting mixture was stirred at room temperature overnight. The resulting mixture was then diluted with EtOAc, washed with H2O, dried over Na2SO4, filtered, and concentrated in vacuo. The resultant residue was purified by flash column chromatography (SiO2), eluting with a hexanes-EtOAc gradient to yield N-cyclopropylmethyl-benzene-1,2-diamine MS 163 (M+1)+ The ice bath was removed The resulting mixture was then diluted with EtOAc washed with H2O dried over Na2SO4 filtered concentrated in vacuo The resultant residue was purified by flash column chromatography (SiO2) eluting with a hexanes-EtOAc gradient
