Reaction Steps
Oxalyl chloride (152 μL; 1.2 mmol; 3 eq.), Intermediate 25 (106 mg; 0.4 mmol; 1 eq.), Intermediate 23 (74 mg; 0.4 mmol, 1 eq.) and DIEA (155 μL; 1.2 mmol; 3 eq.) were reacted according to general procedure 2. Purification by crystallisation from ethyl acetate/n-pentane afforded the title compound as a yellow solid.
