Versuchsvorschrift
A solution of compound 98 (0.415 g, 1.215 mmol) in dry ethanol (20 mL) was treated with thiophene-2-carboximidothioic acid methyl ester hydroiodide (0.693 g, 2.430 mmol) at room temperature and the resulting solution was stirred for 24 h. The solvent was evaporated and crude was diluted with sat. NaHCO3 solution (25 mL) and CH2Cl2 (50 mL). The organic layer was separated and aqueous layer was extracted with CH2Cl2 (2×25 mL). The combined organic layer was washed with brine (20 mL) and dried (Na2SO4). The solvent was evaporated and crude product was purified by column chromatography on silica gel (2M NH3 in methanol: CH2Cl2, 5:95) to obtain compound 99 (0.37 g, 68%) as a foam. 1H NMR (DMSO-d6) δ: 0.85 (t, 1H, J=7.2 Hz), 1.20-1.26 (m, 1H), 1.40 (s, 9H), 1.77-1.87 (m, 2H), 2.22-2.40 (m, 2H), 2.72 (s, 3H), 4.06-4.16 (m, 1H), 6.06 (s, 1H), 6.28 (brs, 1H), 6.66 (d, 1H, J=8.4 Hz), 7.10 (t, 1H, J=4.2 Hz), 7.22 (s, 1H), 7.25-7.32 (m, 2H), 7.60 (d, 1H, J=4.8 Hz), 7.72 (d, 1H, J=3.3 Hz), 10.94 (s, 1H); ESI-MS m/z (%): 451 (MH+, 100).
