2a III 2-04 Intermediate 2a (3.3g) and 2-aminophenol (2g) are added to polyphosphoric acid (2Og) and heated to 150C for 2 hours. The reaction is then cooled to room temperature and then poured onto ice. The mixture is then neutralized with concentrated ammonia. The resulting precipitate is collected via filtration and then dissolved in DCM:EtOH (9:1). The resulting EPO solution is dried over Na2SO4, filtered and the solvent is removed in vacuo to yield the desired compound III (660mg).

Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 334952-09-9.
