Versuchsvorschrift
In a three-necked flask equipped with a gas droplet counter and an efficient cooling system, a mixture of 2,6-dichloro-p-cresol (20.0 g, 113 mmol), [1,3]dioxolan-2-one (9.95 g, 113 mmol) and imidazole (115 mg, 1.70 mmol) was heated to 160° C. for 25 h. The mixture was allowed to cool to rt. Purification by FC (Et2O/heptane 1.1) yielded the title compound (18.7 g, 75%). LC-MS: tR=0.88 min.
