The reaction was microwaved on 300 watts, 100° C. for 45 min. The reaction vessel was resubjected to the microwave heating under the same conditions as before for 45 min. Purification by prep TLC using 4% MeOH in DCM eluting twice afforded 54 mg of the title compound as a yellow solid. MS (ES+): m/z 308.11 (100)[MH+]. HPLC: tR=2.14 min (Open Lynx polar—5 min).
