Reaction Steps

To a solution of cyclopropanecarbaldehyde (0.374 mL, 5 mmol) and methanesulfonamide (0.523 g, 5.5 mmol) in toluene (15 mL) was added titanium(IV) isopropoxide (2.93 mL, 10 mmol), and the mixture was heated to 100° C. for 1 day. The mixture was cooled to room temperature and concentrated in vacuo. The residue was placed under high vacuum for 30 min to give a biphasic mixture. The top layer was discarded. The residue was used in next step without further purification.
