実験手順

A mixture of Example 1B (9.0 g, 35 mmol), potassium cyanate (4.2 g, 52 mmol), and glacial acetic acid (3.1 mL, 52 mmol) in THF (70 mL) and water (7 mL) was stirred at 60° C. for 2 hours, diluted with ethyl acetate, and sequentially washed with saturated aqueous NaHCO3 and brine. The organic layer was concentrated under reduced pressure to provide the title compound. 1H-NMR (DMSO-d6) δ 7.41 (m, 3H), 4.69 (brs, 1H), 4.45 (d, 2H), 4.37 (brs, 2H), 2.64 (ddd, 2H), 1.45 (ddd, 2H), 0.99 (s, 9H).
