To a solution of (6-chloro-1H-indol-3-yl)-[4-(2-fluoro-phenyl)-piperazin-1-yl]-methanone in dry DMF under argon at 0° C. was added (1.1 eq) NaH. The reaction mixture was stirred for 1 h at 0° C. 2,2-Dioxo-2λ6-[1,2,3]oxathiazolidine-3-carboxylic acid tert-butyl ester (1.1 eq) (described in WO 2003037327) was added, and the reaction mixture was stirred for 2 h at RT. After evaporation of DMF, redissolution in dioxan, addition of 5 eq. of HCl (4.0M solution in dioxane) and a few drops of water, the reaction mixture was stirred for 2 h at 50° C.; LC-MS showed complete conversion to the crude product.
