Procedure
Triflic acid (4.09 mL, 46.0 mmol) was added to a solution of N-benzyl-1-chloro-6-methoxy-N-methylisoquinolin-3-amine (1.44 g, 4.60 mmol) in DCM (20 mL) at RT and stirred for 1 hr at RT before reverse adding to a solution of sat. sodium bicarbonate. The organic layer was diluted with DCM and separated. The organic layer was dried over MgSO4, filtered and evaporated. The crude material was purified via silica gel chromatography (90 g column, 0-30% EtOAc:Hex) to give the expected product 1-chloro-6-methoxy-N-methylisoquinolin-3-amine (610 mg, 2.74 mmol, 59.5% yield) as an orange solid. MS: MS m/z 223.15(M++1).
