実験手順

4-(1,3-Dioxoisoindolin-2-yl)-1-methylcyclohexanecarboxylic acid (Intermediate 74, 220 mg, 0.786 mmol) was dissolved in DCM (5 mL), and oxalyl chloride (146 mg, 0.1 mL, 1.149 mmol) was added slowly, followed by addition of a drop of DMF. The mixture was stirred at room temperature for 20 min, then concentrated under vacuum to provide the product as a yellow solid that was used as is in the next step.
