Versuchsvorschrift

4-Fluoro-3-nitro-phenylazide (9.7 mg, 0.053 mmol) and TBTA (1 mg, 0.001 mmol) were added to a solution of compound 218 (14.4 mg, 0.038 mmol) in t-butanol (0.8 mL)-water (0.8 mL) at room temperature. Freshly prepared 1M solution of sodium ascorbate (38.2 μL) followed by 7.5% solution of copper sulfate (63 μL, 0.019 mmol) was also added into the reaction mixture stirred at room temperature overnight. Solvent was evaporated, and the residue was purified on flash silica gel column chromatography (CH2Cl2:MeOH=30:1) to give compound 219a (19 mg, 92%) as a syrup. 1H NMR (CD3OD, 400 MHz) δ 8.62-8.61 (m, 2H), 8.27-8.24 (m, 1H), 8.06 (s, 1H), 7.69-7.64 (m, 1H), 5.08 (d, J=6.8 Hz, 1H), 4.94 (br s, 2H), 4.81 (s, 1H), 4.01 (d, J=6.0 Hz, 1H), 2.87 (s, 3H), 2.07-2.04 (m, 1H), 1.82 (t, J=4.8 Hz, 1H), 1.39-1.37 (m, 1H). HRMS calculated for C22H21ClFN10O5 (M+H)+: 559.1369. Found 559.1346.
