Procedure

A mixture of (3R,4R; 3S,4S)-(2-Amino-4-chloro-phenyl)-{3-[4-(4-chloro-benzyl)-piperazin-1-yl]4-hydroxy-pyrrolidin-1-yl}-methanone trifluoroacetate (22 mg, 0.05 mmol) was dissolved in DMF and acetic anhydride (20 uL, 0.2 mmol) was added. The reaction mixture was shaken for 1 h and directly used for LC-MS purification, to yield 3.2 mg of the title compound as the trifluoroacetate salt. ESIMS ([M+H]+): 491.2 (100).
