The present invention provides novel and advantageous processes for preparing and purifying chemical compounds such as pharmaceuticals. The processes comprise a nucleophilic substitution reaction with a moiety X wherein the leaving group L of a substrate S in the reaction is covalently attached to a purification moiety M. This concept offers a convenient and lime-saving way to purity the desired product S-X from non-reacted precursors S-L-M and by-products L-M.
