실험 절차

In 1 ml of THF was dissolved 31.9 mg of N—[(S)-1-methoxycarbonylethyl]-4-[(S)-3-[(R)-1-(naphthalen-1-yl)ethylamino]pyrrolidin-1-yl]benzamide, 3.0 mg of lithium borohydride was added thereto, and the mixture was stirred at room temperature for 1 day. To the reaction mixture was added a saturated aqueous ammonium chloride solution, and chloroform was added to the mixture and the mixture was stirred and then the liquids were separated. The organic layer was dried and evaporated, and then, the residue was purified by NH silica gel thin-layer chromatography (chloroform:methanol=95:5) to obtain 14.7 mg of N—[(S)-1-hydroxypropan-2-yl]-4-[(S)-3-[(R)-1-(naphthalen-1-yl)ethylamino]pyrrolidin-1-yl]benzamide (the following Table X, Example 12.003).
