Procedure
Preparation analogous to Example 12a) from 2-fluoro-benzaldehyde and 4-tert-butylphenol. Yield: 77%, yellow oil after high vacuum distillation (93°-100° C., 0.9 mbar); TLC (silica gel; hexane/ethyl acetate=1:1; UV): Rf =0.65; 1H-NMR (CDCl3, 200 MHz): 1.35 (s, 9H); 6.75-7.55 (m, 7H); 7.92 (dd, 1H) MS: 254 (M+), 239.
