Procedure

217 mg (0.942 mmol) of N-(tert-butoxycarbonyl)-L-isoleucine together with 246 mg (1.284 mmol) of 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride, 157 mg (1.027 mmol) of 1-hydroxy-1H-benzotriazole hydrate and 0.746 ml (4.281 mmol) of N,N-diisopropylethylamine were dissolved in 7.5 ml of DMF, after which 650 mg (0.856 mmol) of 2-{4-(2-({(2-(4-chlorophenyl)-1,3-thiazol-4-yl)methyl}sulfanyl)-3,5-dicyano-6-(pyrrolidin-1-yl)pyridin-4-yl)phenoxy}ethyl L-alaninate trifluoroacetate were added. After stirring at room temperature overnight, the reaction mixture was purified by preparative HPLC (acetonitrile/water). This gave 414 mg (56% of theory) of the target compound.
