HCID 312751,4-DioxaneSolvent

Procedure

A solution of methyl-4-(4-oxopiperidin-1-yl)-benzoate (4.06 g, 17.40 mmol) and DMF-dimethylacetal (9.32 mL, 69.61 mmol) in 1,4-dioxane (100 mL) was refluxed for 40 hours. The reaction mixture was concentrated and the residue was eluted through a flash column (silica gel 60, 230-400 mesh, 5% MeOH in EtOAc to 8% MeOH in EtOAc) to obtain the title compound as an orange, crystalline solid (3.00 g, 60%).
