Procedure

To a solution of 4-[N′-(2-amino-5-bromo-pyridine-3-carbonyl)-hydrazinocarbonyl]-piperidine-1-carboxylic acid tert-butyl ester (1.3 g, 2.939 mmol) in ACN (50 mL) were added DBU (1.68 g, 11.035 mmol), PPh3 (1.95 g, 7.434 mmol) and CCl4 (4 mL, 41.558 mmol) at RT. The reaction mixture was stirred for 18 h at RT. The reaction mixture was poured into ice-water (30 mL), extracted with ethyl acetate (3×50 mL), organic layer was washed with brine dried over anhydrous sodium sulphate concentrated under reduced pressure. Crude compound was purified by column chromatography using 100-200 mesh silica gel. The column was eluted with 40% EtOAc in petroleum ether to afford the title compound as a white solid.
