Triethylamine → HCID 58822100, compound

Participants

Reaction Steps

The compound (100 mg) obtained in Example 34 was dissolved in pyridine (3 mL), triethylamine (168 μl) and methanesulfonyl chloride (48 μl) were added, and the mixture was stirred overnight at room temperature. The reaction mixture was concentrated under reduced pressure, and methylene chloride and 1N hydrochloric acid were added to the residue to separate an organic layer. The resultant organic layer was dried over sodium sulfate anhydrate. The solvent was distilled away under reduced pressure, and the residue was purified by silica gel column chromatography (methylene chloride:methanol=100:1) to give the title compound (79 mg).
