Reaction Steps

Compound 40 (0.105 g, 0.345 mmol) was dissolved in dichloromethane (10 mL). Trifluoroacetic acid (2 mL) was added in one portion. The mixture was stirred at room temperature for 2 h, and then concentrated under vacuum to dryness. The crude residue was used directly without further purification. 1H NMR (300 MHz, CD3OD): δ 1.60-1.75 (m, 4H), 2.65 (t, 2H), 2.92 (t, 2H), 4.38 (s, 2H), 6.96 (d, 2H), 7.20 (d, 2H). m/z (APCI): 205 [C12H16N2O+H]+.
