Ethyl (2S)-2-(2-chloroacetylamino)-2-(4-fluorophenyl)acetate (400 mg, 1.46 mmol), (2S)-3-(2-methylbenzothiazol-5-yloxy)-1-piperazinylpropan-2-ol (560 mg, 1.46 mmol), and 1.26 ml diisopropylethylamine (7.3 mmol) was refluxed in ethanol for 24 hours. Solvent was removed under reduced pressure, and the residue purified by Prep TLC, to provide ethyl (2S)-2-(2-{4-[(2S)-2-hydroxy-3-(2-methylbenzothiazol-5-yloxy)propyl]piperazinyl}acetylamino)-2-(4-fluorophenyl)acetate.
