To a stirred solution of (6-ethoxy-2-(ethylamino)quinolin-3-yl)methanol SLA 41040 (0.457 g, 1.86 mmol) in dry CH2Cl2 (40 mL) in a 100 mL round-bottomed flask equipped with a magnetic stirrer was added dropwise SOCl2 (2.63 mL, 37.1 mmol). The mixture was stirred for 4 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-ethoxy-N-ethylquinolin-2-amine hydrochloride SLA 41042 as a yellow solid (552 mg, 99% yield).
