A mixture of 4.4 g (15 mmol) of 4-chloro-2-(4-chlorophenyl)-6-fluoroquinoline, 3.9 g (30 mmol) of isonipecotamide, and 6 g of phenol was stirred and heated in an oil bath at 165°-180° for 2 hr. It was then cooled and diluted with 100 ml of water. Crystallization was induced by scratching. The solid was collected and washed with ether to give 5.2 g of crude product, mp 258°-260° dec. Recrystallization from pyridine/water gave off-white needles, mp 259°-261°.
