Procedure

Potassium carbonate (646 mg, 4.67 mmol) was added to a solution of 1,5-dichloroisoquinolin-3-ol (500 mg, 2.336 mmol) and 1-bromo-2-methoxyethane (357 mg, 2.57 mmol) and heated to 50° C. for 3 hrs. After 3 hrs the reaction was diluted with water and extracted with EtOAc (2×). The organic layer was washed with water followed by brine, dried over MgSO4, filtered and evaporated to give the crude product 1,5-dichloro-3-(2-methoxyethoxy)isoquinoline (550 mg, 87% yield), which was used as is in the next step. MS: MS m/z 272.1(M++1).
