Procedure

Nelfinavir free base is slurried or dissolved in a suitable solvent (such as THF, methanol, or ethanol). THF is the preferred solvent. A molar equivalent amount of methanesulfonic acid is added, and the mixture is stirred until all solids dissolve. The solution is added to several volumes of an antisolvent (such as methyl t-butyl ether, diethyl ether, hexanes, or heptanes) that is rapidly stirring. Diethyl ether is the preferred antisolvent. After stirring, the mixture is filtered and washed with antisolvent. The solid is dried in a vacuum oven to yield nelfinavir mesylate.
