78967-07-4, To a cold (ice-bath) solution of 2-(3,4-bis(4-methoxyphenyl)isoxazol-5-yl)acetic acid (mofezolac, 300 mg, 0.885 mmol) and 1,2:3,4-Di-O-isopropylidene-D-galactose (230 mg, 0.885 mmol) in CH2Cl2 (5 mL) , 4-(dimethylamino)pyridine (DMAP) (27 mg, 0.22 mmol), and N-(3-dimethylaminopropyl)-N’-ethylcarbodiimide hydrochloride (EDC HCl, 680 mg, 3.56 mmol) were added in portions under argon atmosphere. The reaction mixture was stirred at room temperature for 24h and then quenched by adding distilled water. The aqueous phase was extracted three times with EtOAc. The combined organic phases were dried over anhydrous Na2SO4, filtered, and the solvent removed under reduced pressure. The product (375 mg) was isolated by column chromatography (silica gel; CHCl3/MeOH 95:5) of the reaction crude. 73% Yield. NMR (300 MHz, CDCl3, delta) : 7.41-7.36 (m, 2H, aromatic protons) ; 7.19-7.14 (m, 2H, aromatic protons) ; 6.94-6.89 (m, 2H, aromatic protons) ; 6.85-6.81 (m, 2H, aromatic protons) ; 5.53 (d, 1H, J = 4.95 Hz) ; 4.61 (dd, 1H, J = 8.0 Hz, J = 2.5 Hz) ; 4.34-4.25 (m, 2H) ; 4.18 (dd, 2H, J = 8.0 Hz, J = 1.9 Hz) ; 4.05-3.99 (m, 1H) ; 3.83 (s, 3H OCH3) ; 3.80 (s, 3H, OCH3) ; 3.79 (s, 2H, CH2) ; 1.45 (s, 6H, 2CH3) ; 1.32 (s, 3H) ; 1.31 (s, 3H) . ESI-MS m/z (%) : C31H35NO10 (M + Na)+: 604.
As the paragraph descriping shows that 78967-07-4 is playing an increasingly important role.
