Participants

Reaction Steps

A stirred mixture of 8-chloro-1-(chloromethyl)-6-(o-chlorophenyl)-4H-s-triazolo[4,3-a][1,4]benzodiazepine (0.004 mole), potassium iodide (0.67 g., 0.004 mole), allylamine (0.84 g., 0.012 mole) and tetrahydrofuran (100 ml.) is kept at ambient temperature (25° C.) for 18 hours and then concentrated in vacuo. The residue is mixed with water and extracted with methylene chloride. The extract is washed with brine, dried over anhydrous sodium sulfate and concentrated. The residue is crystallized from ethyl acetate-Skellysolve B hexanes to give 8-chloro-1-[(allylamino)methyl]-6-(o-chlorophenyl)-4H-s-triazolo[4,3-a][1,4]benzodiazepine. Preparation 39 8-Chloro-1-[(allylmethylamino)methyl]-6-phenyl-4H-s-triazolo[4,3-a][1,4]benzodiazepine
