Reaction Steps

To a solution of 1.63 g of 2,3,5,6,7,8-hexahydro-1-methyl-3-oxoisoquinoline in 10 ml of acetic acid, 1 ml of concentrated sulfuric acid and 5 ml of concentrated nitric acid (d=1.42) were dropwise added under cooling on ice. After the reaction was completed, the reaction mixture was poured into ice water and deposited crystals were filtered out. There was obtained 1.0 g of 2,3,5,6,7,8-hexahydro-1-methyl-4-nitro-3-oxoisoquinoline. mp: 255° C. (decomposition).
