Reaction Steps

Compound 4a (1.02 g, 2.14 mmol) was dissolved in formic acid (10 mL) and stirred overnight at room temperature. The solid was filtered off, the filtrate was evaporated in vacuo, and co-evaporated with toluene (6×20 mL). The pure product obtained was dried overnight in high vacuum. Yield: 0.71 g, 1.95 mmol, 91% (off-white solid). 1H-NMR (DMSO-d6): δ 7.91 (d, 2H, 3JHH=9.0 Hz, ArH), 7.20 (d, 2H, 3JHH=9.0 Hz, ArH), 7.28 (d, 2H, 3JHH=9.0 Hz, ArH), 7.00 (d, 1H, 3JHH=9.0 Hz, ArH), 6.87 (d, 2H, 3JHH=9.0 Hz, ArH), 4.07 (s, 4H, 2×CH2CO2H).
