실험 절차
Oxalyl chloride (138 μL; 1.63 mmol; 3 eq.), Intermediate 35 (120 mg; 0.54 mmol; 1 eq.), Intermediate 1 (90 mg; 0.54 mmol, 1 eq.) and DIEA (280 μL; 1.63 mmol; 3 eq.) were reacted according to general procedure 2. Purification by column chromatography (c-hexane/ethyl acetate, 95/5) afforded the title compound as a yellow solid.
