실험 절차

To a solution of 0.50 g of 6,7-dihydro-5-(2-chloro-4-nitrobenzoyl)-5H-pyrrolo[1,2-a][1,5]benzodiazepine in 10 ml of ethyl alcohol and 2 ml of tetrahydrofuran is added 2.35 g of SnCl2.2H2O and the mixture stirred at 55° C. for 30 minutes. The solvents are evaporated in vacuo to a residue which is stirred with 20 ml of 1N NaOH and 40 ml of ethyl acetate for 15 minutes and filtered through diatomaceous earth. The filter pad is washed with 2×10 ml of ethyl acetate and the combined extracts washed with brine, dried (Na2SO4) and evaporated in vacuo to give 0.47 g of solid residue which is triturated with ether-hexane to give 0.43 g of light yellow crystalline solid. MS(CI): 338(M+H, Cl35) 340(M+H, Cl37)
