After stirring for 16h the reaction was quenched by the addition of water [(20ML).] The phases were separated and the organics were washed with sat. brine [(20ML),] dried and evaporated to dryness under reduced pressure. The residue was purified by chromatography on silica, eluting with 0-10% MeOH/DCM to give 46 as a white solid (0.780g). MS-ESI: 340 (M++H).
