Reaction Steps

A solution of (R)-3-methanesulfonyloxypyrrolidine-1-carboxylic acid tert-butyl ester (2.95 g) in N, N-dimethylformamide (2 ml) was added dropwise to a stirred solution of 1-amino-6-hydroxyisoquinoline (1.2 g, 7.4 mmol) and K2CO3 (1.02 g, 7.4 mmol) in N, N-dimethylformamide (10 ml) at 100° C. The mixture was stirred for 1 h then cooled and water added. The mixture was acidified with glacial acetic acid then diluted with methanol. The mixture was loaded onto a pre-acidified SCX column using methanol and eluted with 2M ammonia in methanol to afford crude (S)-6-(pyrrolidin-3-yloxy)isoquinolin-1-ylamine, which was purified by flash chromatography on silica (eluent: 10% methanol in DCM with 1% ammonium hydroxide), El-MS: m/z=230.3 [M+H]+.
