6-(((Phenylmethoxy)carbonyl)amino)hexanoic acid → HCID 67103490, compound

Participants

Reaction Steps

The compound (510 mg) obtained in Example 46-1 was dissolved in DMF (20 ml). To this solution, a solution which was previously prepared by dissolving 6-benzyloxycarbonylamino-hexanoic acid (1.10 g) in DMF (10 ml), adding thereto WSCI hydrochloride (1.08 g) and HOBt (762 mg), and stirring the mixture for 30 minutes was dropped. The whole was stirred for 20 hours. The residue obtained by distilling the solvent off was subjected to extraction with chloroform. The organic layer was washed with water and a saturated saline solution, and dried with anhydrous sodium sulfate. The residue obtained by distilling the solvent off was purified through silica gel column chromatography (chloroform/methanol), thereby obtaining the subject compound (961 mg) as a white solid.
