A solution of 4-{[(2-fluorophenyl)methyl]oxy}benzaldehyde (D92, 920 mg, 4.0 mmol), prepared by an analogous procedure to that described hereinabove, N1,N2-bis(phenylmethyl)-N1-2-propen-1-ylglycinamide (D90, 588 mg, 2.0 mmol) and DIPEA (0.68 ml, 4.0 mmol) in dry toluene (8 ml) were stirred at 120° C. for 72 h. After the reaction was terminated, it was cooled to room temperature, diluted with ethyl acetate and washed with water and brine. The residue was purified via flash chromatography affording the title compound (503 mg, 50%) as a racemate. Rf (cyclohexanes:ethyl acetate 1:1): 0.57.
