Versuchsvorschrift

(1R,2S,7R,8S)-3-(4-Fluoro-benzyl)-6-hydroxy-5-(7-iodo-1,1-dioxo-1,4-dihydro-1λ6-benzo[1,2,4]thiadiazin-3-yl)-3-aza-tricyclo[6.2.1.02,7]undec-5-en-4-one (prepared as described in Example 19, 0.513 g, 0.864 mmol), sodium azide (1.12 g, 17.2 mmol), sodium ascorbate (0.086 g, 0.43 mmol), copper (I) iodide (0.16 g, 0.84 mmol), and trans-N,N′-dimethylcyclohexane-1,2-diamine (0.20 mL, 1.27 mmol) were dissolved in a 5:1 mixture of dimethyl sulfoxide and water (10 mL) at 25° C. The reaction flask was degassed and backfilled with nitrogen (5×). After stirring at 25° C. for 14 h, the reaction mixture was partitioned between water (150 mL) and ethyl acetate (2×150 mL). The organic layer was dried over sodium sulfate, filtered and concentrated in vacuo. The residue was purified by flash column chromatography (Teledyne Isco RediSep column; 0 to 60% ethyl acetate in hexanes) to afford the desired product, (1R,2S,7R,8S)-5-(7-azido-1,1-dioxo-1,4-dihydro-1λ6-benzo[1,2,4]thiadiazin-3-yl)-3-(4-fluoro-benzyl)-6-hydroxy-3-aza-tricyclo[6.2.1.02,7]undec-5-en-4-one (0.348 g, 0.684 mmol, 79%), as a dark brown foam, which was used in the next step without any further purification.
