実験手順

Intermediate 23 (276 mg; 1.5 mmol; 1 eq.), Intermediate 41 (436 mg; 1.8 mmol; 1.2 eq.) and 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (345 mg; 1.8 mmol; 1.2 eq.) were dissolved in THF (6 mL) and acetonitrile (6 mL) and the reaction mixture was stirred at room temperature for 2 hours. DIEA (0.61 mL; 3.6 mmol; 2.4 eq.) was added and the mixture was heated in the microwave at 150° C. for 30 min. The reaction mixture was then filtered through a SPE-NH2 column (2 g) and through a SPE-SCX column (2 g) and rinsed with ACN. The filtrate was evaporated and the residue washed with ACN to afford the title compound as a white solid.
