Heat the mixture in an oil bath at 120-150° C. overnight (or in microwave reactor for 10-60 min). Dilute the mixture with chloroform/IPA (3/1). Wash the solution with saturated aqueous sodium chloride, dry over sodium sulfate, and concentrate the solution in vacuo to a dark residue. Purify by column chromatography (DCM→10% methanol in DCM) to afford the title compound as a yellow solid (140 mg, 59%). MS (ES) m/z 450 [M+1]+.
