Reaction Steps

9.78 g (40.4 mol) of 6,7-dihydroxyisoquinoline hydrobromide was dissolved under heating in 400 ml of water and treated with 1 g of active carbon. The filtrate thereby obtained was adjusted to pH8.0 with a 8% aqueous ammonia, and the mixture was stirred under cooling with ice. The crystals formed were collected by filtration. They were washed with water and acetone and dried to obtain 6.08 g (yield: 93.4%) of the above identified compound.
