Procedure

1 g (6.016 mmol) of 2,3-dimethyl-4-methoxybenzyl alcohol (Aldrich, Steinheim, FRG) and 4.8 g of diisopropylaminomethylpolystyrene (polyhunig base, see Ex. 44a) in 21 ml of abs. ether are treated dropwise, at from 0° C. to 5° C. and over the space of approximately 25 min, with 0.482 ml of thionyl chloride. After the reaction has ended, the mixture is filtered with suction and the solvent and the excess reagent are removed. The residue, which is the desired title compound, is subjected, without purification, to further processing. TLC Rf (hexane:ethyl acetate 4:1)=0.59. IR(CH2Cl2) inter alia: 1599, 1485, 1466 und 1107 cm-1. 1H-NMR (200 MHz, CDCl3): 7.14 (d, 1H); 6.69 (d, 1H); 4.64 (s, 2H); 3.82, 2.34 and 2.18 (each s, each 3H).
