8-amino quinoline (4.5 g, 31.3 mmol), N-chlorosuccinimide (4.80 g, 36 mmol) was taken up in iPrOH (50 mL) at 60° C. The mixture was heated to reflux and stirred for 20 min. The solution was cooled to 25° C. and concentrated to ⅓ original volume. The mixture was partitioned between CH2Cl2 and water. The aqueous layer was extracted with CH2Cl2. The combined organic layers were dried over Na2SO4, filtered, and concentrated. The crude product was purified by flash chromatography (5:1 hexanes/EtOAc) to afford 1.90 g (34%) of a 8-amino-4-chloroquinoline product.
