Participants

Reaction Steps

The compound obtained in Step 2 of Example 59 (100 mg) was dissolved in chloroform (10 ml). Triethylamine (0.128 ml) and methanesulfonyl chloride (0.036 ml) were added dropwise under ice-cooling, and the mixture was stirred at the same temperature for 10 minutes and then stirred at room temperature for 1.5 hours. The reaction solution was concentrated, and the residue was purified by silica gel column chromatography (developed with methanol-chloroform) to give the title compound (82 mg) as a colorless solid.
