Reaktionsschritte
Oxalyl chloride (190 mg; 1.5 mmol; 3 eq.), Intermediate 31 (149 mg; 0.5 mmol; 1 eq.), Intermediate 23 (92 mg; 0.5 mmol, 1 eq.) and DIEA (194 mg; 1.5 mmol; 3 eq.) were reacted according to general procedure 2. Purification by column chromatography (c-hexane/ethyl acetate, 50/50) followed by crystallisation from Et2O/n-pentane afforded the title compound as a yellow solid.
