Procedure

To a solution of quinoline-6-carboxylic acid (2.0 g, 11.6 mmol) in EtOAc (30 mL) was added carbonyldiimidazole (2.15 g, 13.3 mmol). The resulting mixture was stirred at room temperature for 2 h at which time all solids had dissolved. Benzyl alcohol (1.4 mL) was added and the reaction was stirred overnight. The mixture was then extracted successively with aqueous 1 N HCl (25 mL), aqueous NaHCO3 and brine. Evaporation of the solvent gave a solid, which was triturated with cold 1:1 EtOAc/hexane to afford the title compound as a solid (1.9 g, 62%). 1H NMR (selected signals, CD3OD) δ=9.00 (dd, 1H), 8.61 (d, 1H), 8.34 (d, 1H), 8.29 (dd, 1H), 8.25 (d, 1H), 5.43 (s, 2H)
