Reaction Steps

A mixture of 2-(2-(2-acetoxyethyl)-5-nitro-1-oxo-1,2-dihydroisoquinolin-6-ylamino)ethyl acetate (350 mg, 0.00093 mol), ethanol (20 mL, 0.3 mol), ammonium chloride (496.1 mg, 0.009275 mol) and water (10 mL, 0.6 mol) was added at 85° C. Iron (207 mg, 0.00371 mol) was added in two portions, five minutes apart, and was stirred at that temperature for 1 hour. The reaction mixture was then poured onto methylene chloride (100 mL) and the layers were separated. The organic layer was washed with brine and dried. the solvent was removed under reduced pressureunder reduced pressure and the product was used in the next step without purification.
