Participants

Conditions

Temperature: 65 °C

Procedure

Dimethylformamide dimethylacetal (15 mL) were added to a solution of 7.2 g (0.026 ol) of 1-(3-bromophenyl)-2-pyridin-4-ylethanone in 15 ml of dry tetrahydrofuran. After stirring at 65° C. for 6 hours, the solvent was removed under reduced pressure. 8 g (93% yield) of the title compound as an oil were obtained and employed in the next step without any further purification.
