After cooling the mixture was partitioned between sat. aq. ammonium chloride solution and dichloromethane, the organic layer was separated, washed with brine, dried (MgSO4), and evaporated. Chromatography (SiO2, dichloromethane/methanol 19:1) yielded the title compound (1.28 g, 78%). Yellow solid, ISP-MS: m/e=309.3 ([M+H]+).
