실험 절차

101 mg (0.536 mmol) of N-(tert-butoxycarbonyl)-beta-alanine were initially charged in 2 ml of DMF/dichloromethane (1:1). 44.5 mg (0.232 mmol) of 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride, 10.9 mg (0.89 mmol) of 4-dimethylaminopyridine and 100 mg (0.179 mmol) of 2-(azetidin-1-yl)-6-({(2-(4-chlorophenyl)-1,3-thiazol-4-ylmethyl}sulfanyl)-4-(4-(2-hydroxyethoxy)phenyl)pyridine-3,5-dicarbonitrile (Example 8) were added, and the mixture was then stirred at RT overnight. The crude product was purified by preparative HPLC (acetonitrile/water+0.1% TFA). This gave 118 mg (90% of theory) of the target compound.
