Diethyl Ether → HCID 71145898, compound

Participants

Reaction Steps

To a solution of 3-iodopyridine (0.3 g, 1.463 mmol) in THF (4 ml) was added ethylmagnesium bromide in diethylether (3M) (0.976 ml, 2.93 mmol). The mixture was stirred at room temperature overnight. GC-MS after overnight showed no starting material and the reaction mixture was cooled in an ice-bath. 4-Iodoacetophenone (0.468 g, 1.902 mmol) was added. The ice-bath was removed after 15 minutes and the reaction was stirred at room temperature for 5 hrs. The reaction mixture was quenched with aqueous saturated NH4Cl solution before dilution with ethyl acetate. The organic phase was separated and washed with brine. The organic phase was dried over Na2SO4, filtered and concentrated in vacuo to obtain the crude product which was purified by preparative HPLC (reversed phase). Fractions containing product were pooled and worked up (addition of NaHCO3, removal of acetonitrile followed by extraction with DCM) to obtain the title compound as yellowish oil.
