Reaction Conditions

Reaction Steps

A suspension of 2-bromomethyl-2,3-dihydro-2,4,6,7-tetramethylbenzofuran (1.0 g), N-(diphenylmethyl)-4-piperidinamine (1.5 g), and potassium carbonate (0.77 g) in N,N-dimethylacetamide (4 mL) was stirred under argon gas at 177° C. for 4 hours. This reaction mixture was diluted with water and extracted with ethyl acetate. The extract was washed with water and saturated aqueous sodium chloride solution, dried over MgSO4, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane:ethyl acetate=7:3) to provide the title compound (1.5 g). Yield 97%.
