Synthetic example 1
[0101] Synthesis Example 1: Synthesis of Compound 1-1
[0102]
[0103] A mixture of acetophenone (10 mmol) and DMF-DMA (20 mmol) was refluxed overnight. The reaction mixture was cooled and poured into water, extracted with ethyl acetate, and the organic layer of the extract was washed 3 times with brine, collected and dried over magnesium sulfate. After the solvent was removed, the crude product was purified by silica gel column chromatography with ethyl acetate / n-hexane mixture (50%) as eluent to obtain compound 1a.
[0104]
[0105]
[0106] A solution of the above-mentioned compound 1a in acetic acid / pyridine mixture (4:1) was refluxed overnight. The reaction mixture was cooled and poured into water to precipitate a solid. The solid was collected by filtration, washed thoroughly with water, and dissolved in ethyl acetate. It was washed 3 times with brine, separated and dried over magnesium sulfate. The solvent was evaporated and the crude product was purified ...
