Sterically hindered esterification reactions are best performed in specific fluorous media in the presence of catalytic amounts of diphenylammonium triflate. Fluorous media, in addition to their positive effect on yields, have inherent favorable properties respecting environment and permitting simple work-up. Highly congested reagents, however, react only marginally.

The invention relates to prodrugs of fused heterocyclic inhibitors of D-amino oxidase (DAAO) and methods of treating diseases and conditions, wherein modulation of D-amino acid oxidase activity, D-serine levels, D-serine oxidative products and NMDA receptor activity in the nervous system of a mammalian subject is effective.
Sterically hinderedesters were prepared from the corresponding acyl chlorides and alcohols in the presence of silver cyanide. The method is superior to the conventional acyl chloride–alcohol–pyridine method as regards yield and the rapidity of reaction.
