実験手順

The (R)-2-(4-(cyclopropylsulfonyl)phenyl)-N-(5-fluorothiazol-2-yl)-3-((S)-pyrrolidin-3-yl)propanamide (39.1 mg, 92.3 μmol) obtained in Step 1 of Example 2 was dissolved in ethanol (2 mL), and phenyl N-hydroxycarbamate (56.0 mg, 366 μmol) was then added to the obtained solution. The obtained mixture was stirred for 5 hours at reflux. Thereafter, water was added to the reaction solution, and the mixed solution was then extracted with chloroform. The organic layer was dried over anhydrous sodium sulfate, and was then concentrated in vacuo. The obtained residue was purified by silica gel chromatography (chloroform/methanol=1%→20%) to obtain the captioned compound (24.2 mg, 54%) in the form of a white solid.
