155 °C

A suspension of 6 (50 mg, 0.15 mmol) in PPA was heated to 155° C. for 1 h and then allowed to cool to room temperature. the reaction mixture was carefully diluted using 6% NH4OH aqueous solution to pH=8. The precipitate formed was isolated by filtration to afford 715 mg (33%) as a white solid. HRMS (ESI+): m/z=305.1341 [M+H]
