Procedure

To a stirred solution of methyl (1R,2S,3R,4S)-3-[(4-fluoro-3-methylbenzyl)amino]-7-oxabicyclo[2.2.1]heptane-2-carboxylate (100 mg, 0.34 mmol) and (7-methanesulfonylamino-1,1-dioxo-1,4-dihydro-1λ6-benzo[1,2,4]thiadiazin-3-yl)-acetic acid (prepared as described in Example 1g, 114 mg, 0.34 mmol) in anhydrous N,N-dimethylformamide (4 mL) under a nitrogen atmosphere, N-methylmorpholine (0.075 mL, 0.68 mmol) and 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (72 mg, 0.37 mmol) were added sequentially. The mixture was stirred at 25° C. for 2.5 h, poured into 1.0M aqueous hydrochloric acid solution, and then was extracted with ethyl acetate. The combined organic layers were washed with saturated aqueous brine solution, dried over magnesium sulfate and filtered. The filtrate was concentrated in vacuo to afford the amide intermediate which was used in the next step without further purification.
