실험 절차

A solution of 1-isopropylpiperidine-4-carboxylic acid (2.0 g, 9.6 mol) in methylene chloride (70 mL) was treated dropwise with thionyl chloride (0.70 mL, 9.6 mmol). After heating to reflux for 1 h, 2-amino-N-(5-chloropyridin-2-yl)-4-methoxycarbonylbenzamide (1.5 g, 4.8 mmol) was added. After 0.5 h, pyridine (0.80 mL) was added and the resulting mixture heated at reflux. After 12 h, the mixture was cooled, treated with water, 1 N NaOH (20 mL), and concentrated. The residue was purified by column chromatography (SiO2: 5% methanol:methylene chloride) affording 1.14 g (52%) of the title compound.
