(E)-1-phenylbut-2-en-1-one

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A mixture of 2-hydroxyaniline (2 g), crotonoylbenzene (8.03 g) and concentrated hydrochloric acid (8 ml) was refluxed for 24 hours. The mixture was neutralized with concentrated ammonia water under ice-cooling, and extracted with chloroform. The organic layer was washed with brine, dried over magnesium sulfate and concentrated in vacuo. The residue was purified according to a conventional manner to give 8-hydroxy-2-methyl-4-phenylquinoline (2.4 g) as an oil. was refluxed for 24 hours cooling extracted with chloroform The organic layer was washed with brine dried over magnesium sulfate concentrated in vacuo The residue was purified

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Benzene (1 mL), crotonoyl chloride (236 mg), and aluminium chloride (280 mg) were reacted in dichloromethane (1.5 mL) at from −30° C. to room temperature for 16 hours. The resultant was treated in the same manner as described in Example 1 to obtain the title compound (66 mg). The resultant was treated in the same manner
