Reaction Steps

7.81 g (100 mmol) of benzene and 14.4 g (112 mmol) of ethyl 3,3-dimethylacrylate were reacted analogously with 100 g (5 mol) of liquid hydrogen fluoride and the mixture was stirred at 70° C. for 1 hour. The work-up was carried out analogously to Example A, giving 15.5 g of the compound (3) in a purity of 96% (GC). (Yield: 93.1% of theory). 1H-NMR spectra (100 MHz, CDCl3): 3:7.77-7.25 (m,4H), 2.57 (s,2H), 1.37 (s,6H).
