실험 절차

To a solution of (1S,2R,3S,4R)-3-(4-fluorobenzylamino)-bicyclo[2.2.1]heptane-2-carboxylic acid ethyl ester (100.6 mg, 0.345 mmol) in N,N-dimethylformamide (3.0 mL) was added (7-methanesulfonylamino-1,1-dioxo-1,4-dihydro-1λ6-benzo[1,2,4]thiadiazin-3-yl)-acetic acid (prepared as described in Example 1g, 120.8 mg, 0.362 mmol), 4-dimethylaminopyridine (10.6 mg, 0.086 mmol), and 1-[3-(dimethylamino)propyl]-3-ethylcarbodiimide hydrochloride (70.9 mg, 0.362 mmol). After stirring at 25° C. for 12 h, the mixture was diluted with ethyl acetate and acidified with 1.0 M aqueous hydrochloric acid solution to pH 1. The organic layer was separated and the aqueous layer was extracted with ethyl acetate (2×20 mL). The combined organic layer was dried over magnesium sulfate, filtered, and concentrated in vacuo, and dried under high vacuum to afford the crude product, (1S,2R,3S,4R)-3-{(4-fluorobenzyl)-[2-(7-methanesulfonylamino-1,1-dioxo-1,4-dihydro-1λ6-benzo[1,2,4]thiadiazin-3-yl)-acetyl]-amino}-bicyclo[2.2.1]heptane-2-carboxylic acid ethyl ester, as a faintly yellow oil. The crude product was used in the next step without further purification. LC-MS (ESI) calcd for C27H31FN4O7S2 606.16, found 607.2 [M+H+].
