실험 절차

Methanesulfonic acid (66 mL) was added at room temperature to a suspension of t-butyl[(1R,2S,5S)-2-({[(5-chloropyridin-2-yl)amino](oxo)acetyl}amino)-5-(dimethylaminocarbonyl)cyclohexyl]carbamate (95.1 g) in acetonitrile (1,900 mL), and the mixture was stirred at the same temperature for 2 hours. Triethylamine (155 mL), 5-methyl-4,5,6,7-tetrahydro[1,3]thiazolo[5,4-c]pyridine-2-carboxylic acid hydrochloride (52.5 g), 1-hydroxybenzotriazole (33.0 g), and 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (46.8 g) were added to the reaction mixture under ice-cooling, and the mixture was stirred at room temperature for 16 hours. Triethylamine and water were added thereto, followed by stirring under ice-cooling for 1 hour. The formed crystals were recovered by filtration, to thereby yield 103.2 g of the title compound.
