실험 절차

To a mixture of 2-(2,4-dichloro-6-methylphenoxy)-7-(1-ethylpropyl)-1-methyl-1H-benzimidazole-4-carbaldehyde (120 mg, 0.296 mmol), methyl amine (2M tetrahydrofuran solution, 1.48 ml, 2.96 mmol), acetic acid (0.5 ml) and ethyl acetate (2.0 ml) was added sodium triacetoxyborohydride (314 mg, 1.48 mmol) and the reaction mixture was stirred at room temperature for 48 h. The residue was diluted with aqueous saturated sodium bicarbonate and extracted with ethyl acetate. The extracts were washed with water, dried over magnesium sulfate and concentrated in vacuo. The residue was purified by chromatography on alumina with a 5% ethyl acetate/n-hexane to give 93 mg (0.21 mmol, 70%) of the title compound as a white powder.
