Versuchsvorschrift

Methanesulfonic acid (66 ml) was added to a suspension of tert-butyl [(1R,2S,5S)-2-({[(5-chloropyridin-2-yl)amino](oxo)acetyl}amino)-5-(dimethylaminocarbonyl)cyclohexyl]carbamate (17) (95.1 g) in acetonitrile (1900 ml) at room temperature, and the mixture was stirred at this temperature for 2 hours. To the reaction solution, triethylamine (155 ml), 5-methyl-4,5,6,7-tetrahydro[1,3]thiazolo[5,4-c]pyridine-2-carboxylic acid hydrochloride (13a) (52.5 g), 1-hydroxybenzotriazole (33.0 g), and 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (46.8 g) were added under ice cooling, and the mixture was stirred at room temperature for 16 hours. Triethylamine and water were added thereto, and the mixture was stirred for 1 hour under ice cooling. Then, the crystals were collected by filtration to obtain the title compound (E) (103.2 g).
