Reaction Steps

A mixture of 14.6 g (0.1 mol) of 8-quinolinol, 16 mL of 32% HCl in water, and 16 mL (0.1 mL) of 37% formaldehyde in water at 0° C. was treated with hydrogen chloride gas for 6 h. The solution was allowed to stand at room temperature for 2 h without stirring. The yellow solid obtained was collected on a filter, washed with 90% alcohol and dried under vacuum to give 5-chloromethyl-8-quinolinol hydrochloride A (19.0 g, 98%): 1H NMR (250 MHz, CDCl3, δ) 5.32 (s, 2H), 7.53 (m, 1H), 7.85 (m, 2H), 8.12 (m, 1H), 9.12 (m, 1H), 9.28 (m, 1H).
