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.

The present invention relates to a solid precursor in the form of an organic salt, the solid precursor having a solid support, a method for manufacturing same, and an application thereof. The solid precursor of the present invention enables omission of the [
18
F]fluoride refining process using additional cartridge, and the use of excessive phase-transfer catalyst, and can easily remove remaining substance after reaction through the solid support inside the precursor. The solid precursor of the present invention is very appropriate for an automated synthesis device as an all-in-one system that can carry out overall process of [
18
F]fluorosis reaction, when used by charging in a cartridge.
