Reaction Steps

A mixture of 1.16 g (5.64 mmol) of 2-oxo-1-phenoxycarbonylpyrrolidine (II) were added 2.0 g (8.06 mmol) of 2-(4-methoxyphenyloxy)ethylamine hydrobromide and 1.63 g (16.1 mmol) of triethylamine was heated at 110° C. for 3 hr. After evaporation of the solvent, the residue was refined by silica gel column chromatography, whereby 1.86 g of the objective compound (I a-42) was obtained as crystals from the eluate with toluene/ethyl acetate (5/1-3/1 v/v). Yield: 83.0%
