实验步骤: A mixture of 4-(methylthio)benzylamine (2.00 mL, 2.20 g, 14.38 mmol) and phthalic anhydride (2.39 g, 15.79 mmol) in acetic acid (40 mL, 42 g, 700 mmol) is heated at reflux for 3 h. The mixture is concentrated under reduced pressure, and the residue is partitioned between water and dichloromethane. The phases are separated, and the aqueous phase is extracted twice with dichloromethane. The combined organic layers are concentrated under reduced pressure and the residue is purified by flash chromatography on silica (gradient cyclohexane/ethyl acetate 9:1 to 7:3). Yield: 3.60 g (88% of theory); ESI mass spectrum: [M+H]+=284; r.t. HPLC: 0.75 min (X001_004). is heated at reflux for 3 h The mixture is concentrated under reduced pressure the residue is partitioned between water and dichloromethane The phases are separated the aqueous phase is extracted twice with dichloromethane The combined organic layers are concentrated under reduced pressure the residue is purified by flash chromatography on silica (gradient cyclohexane/ethyl acetate 9:1 to 7:3) r.t 0.75 min (X001_004)

实验步骤: A mixture of 2-(acetylamino)-4-(2-{4-[(tert-butoxycarbonyl)amino]phenyl}ethyl)-1,3-thiazole-5-carboxylic acid (120 mg), [4-(methylthio)benzyl]amine (45.4 mg), 1-hydroxybenzotriazole (44 mg) and 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (59.6 mg) in DMF (2 ml) was stirred at r.t. for 17 hours. The reaction mixture was poured into saturated NaHCO3, and extracted with CHCl3. The organic layer was washed with water and brine, dried over anhydrous MgSO4, and concentrated in vacuo. The residue was purified by preparative silica gel chromatography with CHCl3/AcOEt (1:1) as an eluent to give tert-butyl(4-(2-[2-(acetylamino)-5-({[4-(methylthio)benzyl]amino}carbonyl)-1,3-thiazol-4-yl]ethyl}phenyl)carbamate (163.5 mg) as an off-white solid. extracted with CHCl3 The organic layer was washed with water and brine dried over anhydrous MgSO4 concentrated in vacuo The residue was purified by preparative silica gel chromatography with CHCl3/AcOEt (1:1) as an eluent
