Versuchsvorschrift
Compound 182 (0.053 g, 0.1 mmol) was dissolved in a mixture of methanol (2 mL) and 4M HCl (2 mL). The mixture was stirred and heated to 40° C. for 3 h. The reaction mixture was removed from the heat source and allowed to cool. The reaction mixture was then filtered through a plug of GFA (glass fiber) filter paper and the filtrate concentrated to only remove the methanol. The residue was adjusted to pH 10 by addition of 10% potassium carbonate solution. The resulting solid was collected by filtration and purified by RP-HPLC (C18 Luna column, 10×250 mm, 4.7 mL/min, 10-90% CH3CN in water in 18 min, with all solvents containing 0.05% formic acid) to give compound 176 as a fluffy white solid after lyophilization. 1H NMR (400 MHz, d6-DMSO) δ13.40, br s, 1H; 8.40, s, 1H; 8.35, s, 1H; 7.66, t, J=7.8 Hz, 1H; 7.48-7.58, m, 4H; 7.31-7.36, m, 2H; 7.20-7.23, m, 1H; 5.65, q, J=6.6 Hz, 1H; 2.73, s, 3H; 1.65, d, J=6.6 Hz, 3H.
