Reaction Steps

A solution of 4-[2-(4-fluorobenzyl)-3,3-dimethyl-4-oxo-1,2-diazetidin-1-yl]adamantane-1-carboxylic acid (20.0 mg, 0.0520 mmol) prepared in Example 90 in dichloromethane (1 mL) was added with hydroxybenzotriazole monohydrate (12.0 mg, 0.0890 mmol), WSC.HCl (20.0 mg, 0.100 mmol), 30% aqueous solution of ammonia (0.1 mL) at room temperature, and the resultant was stirred at the same temperature for 30 minutes. The reaction solution was added with water and extracted with chloroform. The organic layer was dried over anhydrous sodium sulfate and concentrated in vacuo. The obtained residue was purified using Preparative Thin-Layer chromatography (ethyl acetate), and the title compound (5.00 mg, 24.9%) was obtained as a white crystalline powder.
