The reaction was heated by microwave at 140° C. for 1.5 h and was monitored by LC/MS. The reaction mixture was evaporated and the solid was extracted with chloroform (100 mL). The solids were removed and the filtrate was evaporated and purified by silica gel chromatography (CHCl3+5% MeOH). Yield 17 mg, 0.03 mmol, 8% as yellow solid.
