Procedure
To a 5 L, 3-necked round bottom flask equipped with overhead stirrer, thermocouple, and nitrogen inlet was added 524 g of the cyano enamide product of Example 14, N-[(1Z)-3-(4-chlorophenyl)-2-(3-cyanophenyl)-1-methylprop-1-en-1-yl]-2-methyl-2-{[5-(trifluoromethyl)pyridin-2-yl]oxy}propanamide, and 112 g K2CO3. DMSO (2.7 L) was charged and the vessel was submerged in a RT water bath. Hydrogen peroxide solution (165 mol of a 30% aqueous solution) was slowly added to the reactor such that the temperature never rose above 25° C. After the addition was complete, the reaction was aged for 1 hour. The batch was diluted with 1 L of isopropyl acetate and filtered over a bed of SOLKA FLOC. The bed was washed with 4.5 L of isopropyl acetate and the resulting solution was transferred to a 50 L extractor containing 5.5 L of water. The layers were separated and the organic layer was washed twice with 3.1 L of water, concentrated to 5 L, and solvent switched to 5 L toluene at −60° C. Upon completion of the solvent switch, 500 mol of heptane was added and the mixture was cooled to 20° C. The batch was aged for 30 minutes at 20° C., then filtered and washed with 1 L of toluene. The resulting solid was dried overnight under a stream of nitrogen to afford 522 g of the title compound (99.4 LCAP, 98.0 wt %, 0.02% dppb-oxide, 512 g assay).
