Procedure

A solution of 4-[methyl-(1-pyrrolidin-3-yl-cyclopropyl)-amino]-piperidine-1-carboxylic acid tert-butyl ester (100 mg, 0.31 mmol) in acetonitrile (30.0 mL) was added 1-cyclopropyl-6,7-difluoro-8-methoxy-4-oxo-1,4-dihydro-quinoline-3-carboxylic acid (98 mg, 0.33 mmol) and DBU (0.23 mL, 1.53 mmol). The suspension was heated to 75° C. overnight. The reaction mixture was partitioned between ethyl acetate and 5% citric acid. The separated organic layer was washed with brine, dried over sodium sulfate and concentrated in vacuo. The residue was purified by preparative thin layer chromatography (10% methanol in dichloromethane) to give the title compound as a yellow solid (102 mg, 62%). ESI MS m/z 599.3 (M+H+).
