Methanol was added and the reaction mixture was evaporated. The solution was taken up in 1N HCl and extracted three times with dichloromethane. The combined dichloromethane layers were extracted with 1N HCl twice and the combined HCl layers were lyophilized, the residue was taken up in water and lyophilized again to yield 1.31 g of 6-(4-methylamino-cyclohexyloxy)-2H-isoquinolin-1-one (152) as hydrochloride. Rt=0.81 min (Method B). Detected mass: 273.2 (M+H+).
