반응 단계
The acid from step 1 (0.702 g, 3.475 mmol) was suspended in DCM (40 mL) under argon, DMF (1 drop) was added and the mixture was cooled in an ice-bath. Oxalyl chloride was added portion-wise over 5 minutes and the mixture was then heated to 40° C. for 90 minutes. On cooling, the solvent was removed to produce 5-bromo-2-pyridinecarbonyl chloride (0.801 g) as a brown solid which was used in step 3.
