Reaction Steps

N-[1-[(3-Methoxyphenyl)methyl]-4-piperidinyl]-8-methoxy-4-[[4-[[[1-(phenylmethyl)-4-piperidinyl]amino]carbonyl]phenyl]amino]-3-quinoline-carboxamide was prepared as a hygroscopic solid (0.76 hydrate) by coupling 8-methoxy-4 -[[4-[[[1-(phenylmethyl)-4-piperidinyl]amino]carbonyl]phenyl]amino]-3-quinolinecarboxylic acid and 1-[(3-methoxyphenyl)methyl]-4-piperidinamine as described for Example 17, Step 5. 1-[(3-Methoxyphenyl)methyl]-4-piperidinamine can be prepared from 3-methoxybenzyl chloride and 1,4-dioxa-8-azaspiro[4.5]-decane as described in U.S. Pat.
