The reaction mixture was allowed to stir at ambient temperature under an inert atmosphere for 24 hours. The reaction mixture was filtered through diatomaceous earth, washing well with DCM and then MeCN. The organics were concentrated and the residue purified by chromatography on silica eluting with DCM:MeOH (9:1) to afford the title compound as a yellow solid (47 mg, 76%);
