Reaction Steps
Oxalyl chloride (106 μL; 1.25 mmol; 3 eq.), Intermediate 24 (120 mg; 0.42 mmol; 1 eq.), Intermediate 1 (69 mg; 0.42 mmol, 1 eq.) and DIEA (93 μL; 1.25 mmol; 3 eq.) were reacted according to general procedure 2. Purification by column chromatography c-hexane/ethyl acetate, 80/20) followed by precipitation from n-pentane afforded the title compound as a white solid.
