Procedure

In 6 ml of tetrahydrofuran was dissolved 615 mg of allyl 2-[4-[(S)-3-[(R)-1-(naphthalen-1-yl)ethyl]aminopiperidin-1-yl]-benzoyl]-D-glucuronate, and the mixture was stirred under ice-cooling and in nitrogen atmosphere. To the mixture were added 91 μl of pyrrolidine, and then, 123 mg of tetrakistriphenylphosphine palladium, and the resulting mixture was stirred for 30 minutes. The residue obtained by concentration under reduced pressure was purified by LC-MS. Ether was added to the obtained solid, the solid was pulverized, collected by filtration, and dried to obtain 220 mg of 2-[4-[(S)-3-[(R)-1-(naphthalen-1-yl)ethyl]aminopiperidin-1-yl]-benzoyl]-D-glucuronic acid (Example 12.030 in the following Table X). (HPLC purity: 67.7%)
