350 mg (0.625 mmol) of 2-(azetidin-1-yl)-6-({(2-(4-chlorophenyl)-1,3-thiazol-4-yl)methyl}sulfanyl)-4-(4-(2-hydroxyethoxy)phenyl)pyridine-3,5-dicarbonitrile (Example 8), 354.7 mg (1.875 mmol) of N-(tert-butoxycarbonyl)-L-alanine and 38.17 mg (0.312 mmol) of 4-dimethylaminopyridine were initially charged in 3.3 ml of DMF. 3.3 ml of THF and 155.7 mg (0.812 mmol) of 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride were added, and the reaction solution was then stirred at 40° C. overnight. After cooling, the reaction solution was purified by preparative HPLC (acetonitrile/water+0.1% TFA). This gave 377 mg (83% of theory) of the target compound.
