Versuchsvorschrift

To a solution containing the compound of Example 111 (0.100 g, 0.124 mmol), N-(tert-butoxycarbonyl) L-alanine (0.028 g, 0.147 mmol)), and 4(dimethylamino)pyridine (0.018 g, 0.147 mmol) in N,N-dimethylformamide (1.0 mL) was added 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (EDAC) (0.029 g, 0.151 mmol) and the mixture was stirred at room temperature for 2 hours. Two subsequent additions of N-(tert-butoxycarbonyl) L-alanine (0.028 g) and 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (EDAC) (0.029 g) were made at two hour intervals. The solvent was evaporated and the reaction mixture was partitioned between ethyl acetate and aqueous NaHCO3. The organic layer was washed with brine, dried over MgSO4, filtered and evaporated. The residue was purified by chromatography on silica gel, eluting with a gradient starting with chloroform and ending with 66% ethyl acetate in chloroform, to give the title compound (0.100 g, 82%).
