Versuchsvorschrift

A solution of 2-methoxy-6-(6-methoxy-4-(prop-2-yn-1-yloxy)benzofuran-2-yl)imidazo[2,1-b][1,3,4]thiadiazole (Example 9A, 20 mgs, 0.056 mmol) and azidobenzene (Example 9B, 19 mgs, 0.159 mmol) in DMF (4 mL, 51.7 mmol) was treated at r.t. and under a nitrogen atmosphere with sodium (R)-2-((S)-1,2-dihydroxyethyl)-4-hydroxy-5-oxo-2,5-dihydrofuran-3-olate (8 mgs, 0.040 mmol) and copper(II) sulfate pentahydrate (5 mgs, 0.020 mmol). The mixture was stirred for 2 hours (reaction followed by HPLC) and was then diluted with dichloromethane (60 mL) and washed with sat. NaHCO3, brine and dried (MgSO4). The solvent was evaporated and the solid residue was triturated with acetonitrile (2×1 mL) and lyophilized to give the title material (13 mgs, 0.027 mmol, 49% yield). LC (Method A): 2.213 min. HRMS (ESI) calcd for C23H19N6O4S [M+H]+ m/z 475.1183, found 475.1204. 1H NMR (DMSO-d6, 400 MHz) δ ppm: 9.04 (s, 1H), 8.37 (s, 1H), 7.90-7.99 (m, 2H), 7.58-7.67 (m, 2H), 7.51 (tt, J=7.4, 1.2 Hz, 1H), 6.97-7.03 (m, 1H), 6.83-6.88 (m, 1H), 6.71 (d, J=1.6 Hz, 1H), 5.38 (s, 3H), 4.20 (s, 3H), 3.83 (s, 3H).
