The mixture was stirred for 1 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 of 3-(chloromethyl)-N-isopropyl-6-methoxyquinolin-2-amine hydrochloride SLA 28190 as a yellow solid (1.79 g, >100% yield).
