Ethylacetate methanol → HCID 59424545, compound

Participants

Reaction Steps

To a solution of 98 (2.44 g, 5.30 mmol) and bromide 97 (1.3 g, 5.07 mmol) in dry toluene (30 mL) was added Pd(PPh3)4 (290 mg, 0.25 mmol). The reaction mixture was heated to reflux for 1.5 h, cooled to room temperature and the solvent was removed under reduced pressure. The resultant solid was purified by column chromatography, eluents EtOAc-Hexane (1:1) then MeOH/EtOAc (20:80), to afford title compound 99 (1.24 g, 71% yield) as a white solid. MS (m/z): 345.1/347.1 (M+H).
