Procedure

A mixture of 250 mg (0.51 mmol) of the 4-bromo-but-2-enoic acid[4-(3-chloro-4-fluoro-phenylamino)-3-cyano-7-methoxy-quinolin-6-yl]-amide, and 103.2 mg (1.02 mmol) of 4-hydroxypiperidine in 2.25 ml dimethylformamide was stirred at room temperature for 3 hr. Saturated sodium bicarbonate was added and the precipitate was filtered and washed with hexane to give the first crop of product. The filtrate was extracted with ethyl acetate and the organic layer with purified by preparative TLC to yield the second crop. The two crops were combined to give 105.8 mg (41%) tan solid: mp >215° C.
