Procedure
Compound 494 (0.03 g, 0.08 mmol) was dissolved in 1,4-dioxan (0.5 mL) and isopropyl isocyanate (0.012 mL, 0.12 mmol) was added. The solution was stirred at 50° C. for 24 h. Isopropyl isocyanate (0.006 mL, 0.06 mmol) was added. The solution was stirred at 50° C. for 24 h. Work up as described in the preparation of compound 259. The crude product was purified by flash chromatography using a gradient of EtOAc/petroleum ether (40-60) 15:85→60:40 as the eluent. This afforded the title compound as a slightly coloured solid. 13C NMR (CD3OD) δ 198.4, 160.9 (dd), 157.8 (dd), 157.4, 151.1, 140.9, 138.7, 136.1, 134.9, 132.6, 131.9, 128.7, 127.3 (dd), 125.9 (dd), 122.4, 120.7, 116.6, 112.9, 112.6 (dd), 105.7 (dd), 42.8, 23.4, 19.6
