Conditions

Temperature: 150 °C

Procedure

245 mg of 2-(4-Methoxy-benzyl)-7-methyl-6-((R)-pyrrolidin-3-yloxy)-2H-isoquinolin-1-one hydrochloride were dissolved in 1.4 g trifluoroacetic acid and the mixture was heated for 2 h in a microwave oven at 150° C. Then the excess trifluoroacetic acid was distilled off in vacuo and the residue was diluted with 10 ml 1 M hydrochloric acid. The aqueous phase was washed with methylene chloride twice and then it was freeze dried to give 134 mg 7-Methyl-6-((R)-1-pyrrolidin-3-ylmethoxy)-2H-isoquinolin-1-one hydrochloride. Rt=0.92 min (Method B). Detected mass: 245.1 (M+H+).
