Reaction Steps

7-(2,2-Dimethoxy-ethoxy)-2-(4-isopropyl-thiazol-2-yl)-8-methyl-quinolin-4-ol (875 mg, 2.3 mmol) was dissolved in pyridine (20 mL). POCl3 (4.2 ml, 46.0 mmol) was added slowly. The reaction was heated at 80° C. for 4 hours. The reaction was cooled to 0° C. and methanol (5 mL) was added. The reaction was neutralized with a saturated aqueous sodium bicarbonate solution. The product was extracted with ethyl acetate (3×20 mL). The combined organics were dried with sodium sulfate, filtered and was concentrated. 4-Chloro-7-(2,2-dimethoxy-ethoxy)-2-(4-isopropyl-thiazol-2-yl)-8-methyl-quinoline (410 mg, 44%) was purified by silica gel chromatography.
