1-Amino-6-hydroxyisoquinoline (50 mg, 0.312 mmol), prepared as described in WO 00/24718 (Akzo Nobel N.V.), and 2-tert-butylimino-2-diethylamino-1,3-dimethyl-perhydro-1,3,2-diazaphosphorine on polystyrene (284 mg, ˜2.2 mmol.g−1, ˜0.624 mmol) were stirred at ambient temperature in acetonitrile (4 ml) for 15 min. (R) Methanesulfonic acid 1-benzylpyrrolidin-3yl ester (0.312 mmol) was added and the mixture heated to 110° C. and stirred for 60 h. The mixture was filtered and the precipitate washed with acetonitrile. The filtrate was concentrated and then purified by prep-HPLC to give (S)-6-(1-Benzylpyrrolidin-3-yloxy)-isoquinolin-1-ylamine (40 mg),
