실험 절차

To a stirred solution of methyl 10-chloro-1-(2-chloro-4-methoxyphenyl)-2,3,4,5-tetrahydro-1H-[1,3]diazepino[1,2-a]benzimidazole-7-carboxylate (336 mg, 0.800 mmol) in tetrahydrofuran (6 mL) was added lithium borohydride (69.7 mg, 3.20 mmol) at 0° C. After being stirred for 20 h at 60° C., the reaction mixture was diluted with ethyl acetate, quenched with aqueous ammonium chloride, washed with water and brine, dried over sodium sulfate, filtrated, and concentrated in vacuo to give the title compound as a colorless solid (318 mg, 0.798 mmol, 99%).
