実験手順
After dissolving 4-{[({[2-(carbamoylmethyl)phenyl]amino}thioxomethyl)amino]methyl}piperidine carboxylic acid tert-butyl ester (410 mg, 1.01 mmol) in tetrahydrofuran (15 mL), N,N′-dicyclohexylcarbodiimide (208 mg, 1.01 mmol) was added and the mixture was stirred at room temperature for 6 hours. The filtrate obtained by filtering the insoluble portion was concentrated under reduced pressure, and the concentrate was suspended in a solution of n-hexane:ethyl acetate=1:2 (3 mL). The insoluble portion was refiltered, and the residue obtained by concentrating the filtrate under reduced pressure was purified by silica gel column chromatography (n-hexane/ethyl acetate=2/3→1/2) to obtain the title compound. Yield: 193 mg (51%).
