The mixture was heated to reflux for 1 hour, the catalyst was removed by filtration and the filtrate evaporated under reduced pressure. Trituration with ether gave an off-white solid which was purified by reverse phase HPLC (SiO2) using methanol:chloroform as eluant. Recrystallisation from isopropyl alcohol gave the subtitled compound as a buff coloured solid.
