Reaction Steps
A mixture of tert-butyl {1-[2-(5-cyano-7-fluoro-2-oxoquinolin-1(2H)-yl)ethyl]piperidin-4-yl}carbamate and tert-butyl {1-[2-(7-cyano-5-fluoro-2-oxoquinolin-1(2H)-yl)ethyl]piperidin-4-yl}carbamate (Intermediates 173 and 174, 170 mg, 0.41 mmol) was reacted with trifluoroacetic acid in dichloromethane as described for Intermediate 140 to give 120 mg (92% yield) of the mixture of regioisomers as an oil. This mixture was carried on without further purification to the next step.
