The solvent was evaporated at reduced pressure. 90 mL of brine was added to the residue and the mixture was extracted with 3×40 mL of ethyl acetate. The organic layer was washed with 3×20 mL of water and 20 mL of brine, and dried over sodium sulphate. The solvent was removed at reduced pressure and the residue purified by flash chromatography (petroleum ether/ethyl acetate gradient 95:5 to 80:20). The solvents were removed in vacuo to give 1.86 g (52%) of Compound 4B as a white solid. M.p. (98) 102-105° C.
