To a stirred solution of (6-methoxyquinolin-3-yl)methanol SLA 47088A (0.476 g, 2.5 mmol) in dry CH2Cl2 (25 mL) in a 100 mL round-bottomed flask equipped with a magnetic stirrer was added dropwise SOCl2 (3.65 mL, 50.4 mmol). The mixture was stirred for 2 h at RT then concentrated to dryness at 40° C. under vacuum. The residue was then taken up in CH2Cl2 (20 mL) before concentration back to dryness at 40° C. under vacuum (done 3 times) to give 3-(chloromethyl)-6-methoxyquinoline hydrochloride SLA 47088B as a yellow solid (0.60 g, 98% yield).
