Reaction Steps

A mixture of 2-bromo-N-((7-chloro-4-oxo-1-phenyl-1,4-dihydroquinolin-3-yl)methyl)-thiazole-5-carboxamide (intermediate F) (30 mg, 0.063 mmol) and piperidine (10.8 mg, 0.126 mmol) in NMP was heated to 120° C. in a sealed microwave tube. After heating for 2 hr., the mixture was allowed to cool to room temperature. The crude product was purified using preparative reverse-phase HPLC, providing 2-piperidin-1-yl-thiazole-5-carboxylic acid (7-chloro-4-oxo-1-phenyl-1,4-dihydro-quinolin-3-ylmethyl)-amide. MS calcd. for C25H23ClN4O2S [(M+H)+] 479.1, obsd. 478.
