Procedure

2-Methylpropanoic acid (5 mL) and silver (I) oxide (2.3 g) were charged to a vessel at room temperature. 1-Chloro-2-methylpropyl (4-methylthiophenoxy)formate (2.46 g) D4 was added to the reaction vessel. The reaction was heated to 95° C. and the mixture was maintained at approximately 90° C. for 1 hour. The reaction was then cooled to room temperature and tert-butyl methyl ether (20 mL) was added. The solid was filtered and the filter was washed with tert-butyl methyl ether (2×15 mL). The organic phase was washed with water (4×25 mL), bicarbonate (2×25 mL), and dried over sodium sulfate. The organic volatiles were removed under vacuum to provide 3.2 g of the title compound D5 as a pale-yellow oil.
