Procedure

A still further embodiment is directed to a process for preparing N-(2-hydroxyethyl)-N-methyl-4-(quinolin-8-yl(1-(thiazol-4-ylmethyl)piperidin-4-ylidene)methyl)benzamide comprising reacting 2-(methylamino)ethanol with 4-((1-(tert-butoxycarbonyl)piperidin-4-ylidene)bromomethyl)benzoic acid to form tert-butyl 4-((4-(N-(2-hydroxyethyl)-N-methylcarbamoyl)phenyl)bromomethylene)piperidine-1-carboxylate; reacting the tert-butyl 4-((4-(N-(2-hydroxyethyl)-N-methylcarbamoyl)phenyl)bromomethylene)piperidine-1-carboxylate with 8-quinolineboronic acid to form tert-butyl 4-((4-(N-(2-hydroxyethyl)-N-methylcarbamoyl)phenyl)(quinolin-8-yl)methylene)piperidine-1-carboxylate; deprotecting the tert-butyl 4-((4-(N-(2-hydroxyethyl)-N-methylcarbamoyl)phenyl)(quinolin-8-yl)methylene)piperidine-1-carboxylate to form N-(2-hydroxyethyl)-N-methyl-4-((piperidin-4-ylidene)(quinolin-8-yl)methyl)benzamide; and reacting the N-(2-hydroxyethyl)-N-methyl-4-((piperidin-4-ylidene)(quinolin-8-yl)methyl)benzamide with thiazole-4-carbaldehyde to form the N-(2-hydroxyethyl)-N-methyl-4-(quinolin-8-yl(1-(thiazol-4-ylmethyl)piperidin-4-ylidene)methyl)benzamide.
