実験手順

The title compound was prepared according to the procedure as described in Gilman, H., et al., J. Am. Chem. Soc., 1935, Vol. 57, pp 909-912, more particularly, as described on page 910) by treating a dilute aqueous NH3 solution (made by dilution of 1 mL of 29.3% aqueous NH3 with 9 mL of H2O) of 5-bromo-4-tert-butyl-furan-2-carboxylic acid (500 mg, 2.02 mmol, prepared as described in Example K, Step B) with Zn dust (265 mg, 4.05 mmol) to yield the title compound. 1H-NMR (400 MHz, CDCl3) δ: 7.40 (d, J=1.0 Hz, 1H), 7.28 (d, J=1.2 Hz, 1H), 1.26 (s, 9H).
