Participants

Reaction Steps

3-(S)-Amino-1-(1-chloro-isoquinolin-7-ylmethyl)-pyrrolidin-2-one hydrochloride (1.74 g, 5.6 mmol) is suspended in CH3CN (120 mL). To this solution is added triethylamine (2.35 mL, 16.9 mmol) followed by 7-methoxynaphthalene-2-sulfonyl chloride (1.52 g, 5.93 mmol). The mixture is stirred overnight, then concentrated to dryness. The crude product is purified by column chromatography eluting with a gradient of 2% MeOH/CH2Cl2 to 5% MeOH/CH2Cl2 to give the title compound (2.7 g, 5.4 mmol) as a light yellow solid.
