Procedure

The compound (870 mg, 2.67 mmol) obtained in Step 1 above was dissolved in N,N-dimethylformamide (30 ml), 1-hydroxybenzotriazole (361 mg, 2.67 mmol) and 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (614 mg, 3.20 mmol) were added and the resulting mixture was stirred at room temperature for 15 minutes. Ammonium chloride (285 mg, 5.44 mmol) and N,N-diisopropylethylamine (1.86 ml, 10.7 mmol) were added and the resulting mixture was stirred at room temperature for 8 hours. The reaction mixture was diluted with ethyl acetate and the organic layer was washed with saturated sodium bicarbonate solution and brine in that order and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure to give 495 mg (57%) of the title compound as a colorless solid.
