Cyclopentylideneacetonitrile → HCID 59402390, compound

Participants

Reaction Steps

A mixture of cyclopentylideneacetonitrile (0.65 g, 0.0061 mol), 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (0.60 g, 0.0031 mol, Aldrich, Cat. 525057), and 1,8-diazabicyclo[5.4.0]undec-7-ene (47 mg, 0.00031 mol, Aldrich, Cat. No. 139009) in acetonitrile (7 mL) was stirred at 60° C. overnight. After cooling to r.t., the reaction mixture was concentrated. The crude residue was purified by flash column chromatography on a silica gel column using 40% ethyl acetate in hexane as eluent to afford the desired compound (161 mg, 17.29%). LCMS (M+H)+: m/z=302.4.
