Reaction Steps

A solution of (S)-(9H-fluoren-9-yl)methyl 1-(1,8-dichloroisoquinolin-3-yl)ethylcarbamate 69 (250 mg, 0.539 mmol, 1.0 eq) and 1-methylpiperazine (108 mg, 1.079 mmol, 2.0 eq) in 1,4-dioxane (5 mL) was stirred at reflux overnight. The reaction mixture was allowed to cool to RT and concentrated in vacuo. The residue was purified by flash column chromatography on silica gel (3.3% MeOH-DCM) to afford the product (S)-1-(8-chloro-1-(4-methylpiperazin-1-yl) isoquinolin-3-yl)ethanamine 95.
