Versuchsvorschrift

The title compound of Example 6 (1.77 g, 10.2 mmol, 1.02 eq) was combined with thiourea (0.76 g, 9.98 mmol, 1 eq) under N2 in 10 mL of absolute ethanol. The reaction was heated at reflux for 1.5 hours. The mixture was cooled to room temperature and concentrated in vacuo. Trituration of the resulting crude material with t-butyl methyl ether provided 2.32 g (93%) of the title compound. HPLC R.T.=2.05 min (Phenomenex Inc., 5 μm C18 column 4.6×50 mm, 10-90% aqueous methanol over 4 minutes containing 0.2% phosphoric acid, 4 mL/min, monitoring at 220 nm); 1H NMR (d6-DMSO): δ 9.48 (s, 3H), 6.85 (s, 1H), 4.73 (s, 2H), 1.24 (s, 9H).
