Triphenylphosphine → HCID 68294314, compound

Participants

Reaction Steps

Triphenylphosphine (393 mg, 1.5 mmol) and (E)-methyl 3-(1H-pyrazol-4-yl)acrylate, prepared as described above, (12 mg, 1 mmol) were added to a solution of N-methyl-4-hydroxymethyl-piperidine (165 mg, 1.25 mmol) in tetrahydrofuran (THF, 2 mL). After addition of di-tert-butyl azodicarboxylate (345 mg, 1.5 mmol), the reaction was stirred overnight at room temperature. Solvents were evaporated under reduced pressure and the residue was purified by silica gel chromatography using a gradient of Hexane in EtOAc from 1:1 to 0:100 v/v. Fractions containing product were pooled and evaporated to give 220 mg of pure material (0.84 mmol, 84%).
