반응 단계
Oxalyl chloride (190 mg; 1.5 mmol; 3 eq.), Intermediate 8 (132 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, 80/20) followed by crystallisation from ethyl acetate/n-pentane afforded the title compound as a yellow solid.
