A suspension of compound 12 (0.041 g, 0.10 mmol) and trimethyltin azide (0.023 g, 0.11 mmol) in toluene (2 mL) was refluxed for 15 h. The reaction mixture was allowed to stand at rt for 48 h. The resulting suspension was filtered and washed with toluene (2×). The solid was treated with hydrogen chloride (4 M in dioxane, several mL) for 4 h at rt. The reaction mixture was concentrated on a rotary evaporator. The residue was purified by reverse phase HPLC (C18 column, water/acetonitrile gradient containing 0.05% trifluoroacetic acid) to afford 13 as a white solid (0.009 g, 20%). 1H NMR (CDCl3) δ 8.22 (br s, 1H), 8.05 (br m, 1H), 7.82 (br m, 3H), 7.52-7.38 (m, 5H), 7.30 (br m, 2H), 5.23 (s, 2H), 4.53 (br m, 1H), 2.27 (br m, 4H), 2.06 (br m, 2H), 1.84 (br m, 1H), 1.40 (br m, 3H); ESI-MS m/e 451.3 (M+1); HPLC purity (ELSD)>95%.
