Procedure

7-Chloro-4-[[4-[[[1-(phenylmethyl)-4piperidinyl]amino]carbonyl]phenyl]amino]-3-quinolinecarboxylic acid ethyl ester (51.7 g, 95.2 mmol) was stirred in 550 ml of methanol and treated with 133 ml of 2.5 M NaOH. The reaction mixture was then refluxed for 45 m at which point the hot homogeneous solution was treated with 166 ml of 2 M HCl to precipitate the product. After the mixture cooled to room temperature, the product was filtered and washed with water, methanol and then ether. The yellow powdery material was then dried in vacuo overnight affording 31.3 g (60.9 mmol, 64% yield) of 7-chloro-4-[[4-[[[1-(phenylmethyl)-4-piperidinyl]amino]carbonyl]phenyl]amino]-3-quinolinecarboxylic acid.
