反応手順
3,5-Dichloropyridine-4-carboxylic acid (0.5 g, 2.6 mmol; Reference Example 1) was dissolved in CH2Cl2 (1.75 mL) and DMF (50 μL). Thionyl chloride (0.21 mL, 2.86 mL) was added and the reaction mixture was heated at 50° C. for 20 h. The residue was concentrated in vacuo. The formation of the acid chloride was observed by TLC (50% EtOAc/hexane) and the crude 3,5-dichloropyridine-4-carboxylic acid chloride was used in Step E without further purification.
