실험 절차

A suspension of ethyl 4-hydroxy-8-iodo-6-(tetrahydro-2H-pyran-4-ylmethyl)-3-quinolinecarboxylate (0.8 g) and 4-chlorobenzylamine (1.54 mL) is heated to 180° C. for 1 h. The reaction is cooled to room temperature. The resulting solid is collected and washed with Et2O. The crude solid is adsorbed onto silica and chromatographed (Biotage flash 40S, eluant 1% MeOH/CH2Cl2 then 2% MeOH/CH2Cl2). Fractions homogeneous by TLC are combined and concentrated. The resulting solid is triturated with EtOAc/hexanes to yield 0.73 g (75%) of N-(4-chlorobenzyl)-4-hydroxy-8-iodo-6-(tetrahydro-2H-pyran-4-ylmethyl)-3-quinolinecarboxamide as a white solid, m.p. 257-259° C.
