3336-43-4, 1-Chloroisoquinolin-4-ol is a isoquinoline compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Step 1 1-chloroisoquinolin-4-ol (0.5 g, 2.78 mmol), 1-bromo-2-methoxyethane (0.318 mL, 3.34 mmol), and potassium carbonate (0.539 g, 3.90 mmol) were added to a solution of DMF (10 mL) and heated to 45 C. for 1 hr. Ater 45 min, the temp was raised to 55 C. for 45 min. One half of an equivalent of 1-bromo-2-methoxyethane (0.318 mL, 3.34 mmol) was then added and then stirred at 40 C. for overnight. The reaction was diluted with water and extracted with EtOAc. The organic layer was washed with brine, collected, dried over MgSO4, filtered and evaporated to give the crude product. Crude material purified via silica gel chromatography (10-60% EtOAc:Hex) to give the desired product 1-chloro-4-(2-methoxyethoxy)isoquinoline (368 mg, 1.548 mmol, 55.6% yield) as an orange solid. 1H NMR (400 MHz, CHLOROFORM-d) delta 8.33-8.24 (m, 2H), 7.83 (s, 1H), 7.81-7.68 (m, 2H), 4.40-4.32 (m, 2H), 3.95-3.84 (m, 2H), 3.52 (s, 3H). MS: MS m/z 238.15 (M++1).
3336-43-4, As the paragraph descriping shows that 3336-43-4 is playing an increasingly important role.
