Reaction Steps

(RS)-3-[2-(4-Fluorophenyl)-2-oxo-ethoxycarbonylmethyl]-piperazine-1-carboxylic acid tert-butyl ester description 110 (0.887 g) was reacted with HATU (0.932 g), diisopropylethylamine (1.30 ml) and 5-(4-fluoro-phenyl)-2-methyl-thiazole-4-carboxylic acid (0.707 g) in dry DMF (8 ml) according to the method of description 20. Silica gel column chromatography, eluting with ethyl acetate-hexane mixtures provided the title compound as a white foam (1.168 g), mass spectrum (API+) 600 [MH+], C30H31F2N3O6S requires 599.
