실험 절차

Add isobutyl isocyanate (77 mg, 0.78 mmol) to a solution of 4-(4-{(1E)-4-[9-(aminoacetyl)-2,9-diazaspiro[5.5]undec-2-yl]but-1-en-1-yl]-2-methylbenzyl}-5-(propan-2-yl)-1H-pyrazol-3-yl 2,3,4,6-tetra-O-acetyl-beta-D-glucopyranoside dihydrochloride (350 mg, 0.39 mmol) and diisopropylethylamine (302 mg, 2.34 mmol) in dichloromethane (1.0 mL). After 30 min at room temperature, concentrate to dryness under the reduced pressure. Treat the residue with 2.0 M NH3/methanol (1.0 mL) for 3 hours at room temperature, remove the solvent under the reduced pressure. Purify the resulting residue by preparative HPLC method: high pH, 29% B for 4 min, 29-44% B for 5 min @ 85 mL/min using a 30×75 mm, 5 um C18XBridge ODB column, solvent A—H2O w NH4HCO3 @ pH 10, solvent B—acetonitrile to yield the title compound as solid (134 mg, 0.18 mmol). MS (m/z): 755.2 (M+1), 753.2 (M−1).
