In a manner similar to the method described in example 130a, 5-ethyl-2-hydroxy-benzaldehyde (4.75 g, 31.7 mmol) was reacted with K2CO3 (13.1 g, 95.1 mmol) and (2-bromo-ethoxy)-tert-butyl-dimethyl-silane (9.09 g, 38.0 mmol) to give 2-[2-(tert-Butyl-dimethyl-silanyloxy)-ethoxy]-5-ethyl-benzaldehyde as dark brown oil (9.0 g, 92.7%).
