Procedure

A solution of 2.0 g of 2,6-difluorobenzoylisocyanate in 5 ml of a 1:1 v:v mixture of toluene and petroleum ether was added at room temperature over 30 minutes to a stirred solution of 4.4 g of 33 in 20 ml of the same solvent. After stirring at room temperature for 2 hours, the mixture was filtered, and the collected solid product was recrystallized from a mixture of diethyl ether and petroleum ether to give 36, as a white solid, m.p.: 136°-138° C.
