Methyl iodide → 1H-1,4-Benzodiazepine

참여 물질

반응 단계

A stirred solution of 8-chloro-1-[(aminooxy)methyl]6-phenyl-4H-s-triazolo[4,3-a][1,4]benzodiazepine (0.02 mole) in dry dimethylformamide (50 ml.) is cooled in an ice bath under nitrogen and treated successively with a 57% mineral oil suspension of sodium hydride (0.84 g,. 0.02 mole) and methyliodide (0.02 mole). The mixture is allowed to come slowly to ambient temperature and stand for 18 hours. It is then concentrated in vacuo. The residue is chromatographed on silica gel with methanol to give 8-chloro-1-[[(methylamino)oxy]methyl]6-phenyl-4H-s-triazolo]4,3-a][1,4]benzodiazepine.
