実験手順

To a solution of [3-(5-{3-chloro-4-[(1-methylethyl)oxy]phenyl}-1,3,4-thiadiazol-2-yl)-2-ethylphenyl]acetaldehyde (D15) (73 mg) and methyl 3-azetidinecarboxylate (138 mg) in methanol (10.00 mL) stirred at room temperature was added sodium acetate (74.7 mg) and AcOH (0.15 mL). The reaction mixture was stirred at room temperature for 10 min. The residue was dissolved in dichloromethane (DCM) (10 mL), and sodium triacetoxyborohydride (116 mg) was added. Stirring continued for overnight. Water was added to quench the reaction, and DCM was removed by evaporation. The mixture was extracted by EA for 3 times. The combined organic solution was washed by brine, dried over anhydrous Na2SO4. The dried solution was filtered and concentrated to give methyl 1-{2-[3-(5-{3-chloro-4-[(1-methylethyl)oxy]phenyl}-1,3,4-thiadiazol-2-yl)-2-ethylphenyl]ethyl}-3-azetidinecarboxylate (D17) (18.21 mg). MS (ES): C26H30ClN3O3S requires 499. found 500.2 (M+H+).
