Procedure

Under a nitrogen atmosphere 59 mg (1.4 mmol) sodium hydride were added at 0° C. to 0.50 g (1.2 mmol) (2R)-tert-butyl-2-(cycloheptylmethyl)-5-(3,5-difluorophenyl)-3-oxopiperazine-1-carboxylate (isomer 4.1) in 20 ml DMF. After 20 min at 0° C. 0.13 ml (1.4 mmol) methyl bromoacetate were added and the mixture was stirred for 30 min at 0° C. Then the reaction mixture was stirred for 5 h at RT. The reaction mixture was mixed with water and extracted twice with ethyl acetate. The combined organic phases were dried and evaporated down.
