Reaction Steps

To a solution of N-(6-hydroxyisoquinolin-1-yl)-benzamide (100 mg, 0.379 mmol), triethylamine (105 mL, 0.758 mmol) and pyridine (306 mL, 3.79 mmol) in anhydrous tetrahydrofuran (2 ml) was added N,N-dimethylthiocarbamoyl chloride (70 mg, 0.568 mmol) at 0° C., under nitrogen. The mixture was heated to 65° C. and stirred for 48 h. The organics were removed under reduced pressure and excess pyridine was removed by azeotroping with toluene (x 2). Saturated aqueous NaHCO3 was added and the mixture was extracted with dichloromethane (x 2), dried (magnesium sulphate) and concentrated in vacuo to give a residue. Flash chromatography of the residue (eluent: 5-50% ethyl acetate in heptane) gave dimethylthiocarbamic acid O-(1-benzoylaminoisoquinolin-6-yl)ester (70 mg), EIMS: m/z=352.7 [M+H]+.
