Participants

Reaction Steps

0.4 g of A3 are dissolved in 4 ml of ethanol and mixed at room temperature with 4 ml of 15% HCl in ethanol. After concentrating by evaporation on a rotary evaporator, a white solid is obtained (0.44 g), which is recrystallised from 2 ml of isopropanol. The title compound A4 is thus obtained as a white solid (0.2 g, 40%). Melting point 154° C. 1H-NMR (400 Hz, DMSOd6) δ: 1.13 (1H); 1.38 (3H); 2.05 (2H); 2.25 (1H); 2.52 (3H); 3.43 (1H); 4.35 (1H); 5.92 (1H); 8.57 (2H).
