On cooling, methanol (5 ml) was added and after stirring for 10 minutes the solvent was evaporated. The title compound was isolated by MPLC (20% MeOH/CH2Cl2, Merck 9385 silica) and crystallised on evaporating the fractions to a small volume. The title product was filtered off washed with. a little cold methanol (150 mg, 56%).
