Reaction Conditions

Reaction Steps

A mixture of tert-butyl 4-fluorobenzoate (2.14 g) and 1-(2-aminoethyl)pyrrolidine (1 mL) is stirred at 120° C. for one day. After cooling, to the reaction mixture is added water and the mixture is extracted with ethyl acetate (×2). The extract is concentrated by centrifugal concentrator and the residue is purified by flash column chromatography on NH-silica gel (Solvent; n-hexane:ethyl acetate=8:1→4:1) to give tert-butyl 4-[[2-(1-pyrrolidinyl)ethyl]amino]benzoate (1.62 g, yield; 51%) as an oil. MS (APCI) m/z: 291 [M+H]+
