Reaction Steps

Compound 494 (0.055 g, 0.15 mmol) was dissolved in dry pyridine (0.3 mL) and isocyanatoethyl methylacrylate (0.031 mL, 0.22 mmol) was added. The solution was stirred at room temperature for 1 h. H2O was added and the water phase was extracted with EtOAc (×2). The combined organic phases were washed with brine, dried (MgSO4), filtered and concentrated in vacuo. The crude product was purified by flash chromatography using EtOAc/petroleum ether (40-60) 2:1 as the eluent. This afforded the title compound as oil. 13C NMR (CDCl3) δ 196.5, 167.5, 159.2 (dd), 155.8, 155.6 (dd), 148.2, 139.7, 136.3, 135.9, 135.1, 133.9, 132.4, 132.0, 128.6, 126.1, 124.5 (dd), 124.2 (dd), 123.3, 121.2, 116.3, 112.7, 111.6 (dd), 104.9 (dd), 63.9, 39.3, 19.6, 18.2
