m-Chloroperbenzoic acid → HCID 18546546, compound

To an ice-cold solution of 3-methylthio-1-propyl acrylate (18) (5.95 g, 37.1 mmol) in CH2Cl2 (80 mL), m-chloroperoxybenzoic acid (76.5 wt % 8.37 g, 37.1 mmol) was added in portions over a period of 1.5 hours. The progress of the reaction was monitored by TLC. Upon completion of the reaction, the solvent was evaporated under reduced pressure. The resulting sticky white solid was washed with water (2×100 mL) and filtered. The water washings were evaporated under reduced pressure to yield the crude product as a yellow oil. The crude product was purified by column chromatography (silica gel, ether, 20 wt % acetone/ether, 70 wt % acetone/ether) to afford colorless oil compound 23, namely methyl 3-(acryloyloxy)propyl sulfoxide (4.3 g, 66 wt %) (23).
