Versuchsvorschrift

A solution of 2.0 g (9.0 mmol) of 5-tert-butyl-2-methyl-4-thiocyanato-phenol (prepared in Example GGG), imidazole (0.800 g, 11.8 mmol) and DMF (10 mL) was treated with t-butyldimethylsilylchloride (1.64 g, 10.9 mmol) and stirred overnight. The mixture was diluted with saturated sodium bicarbonate and the mixture extracted with hexanes. The hexane layers were combined, dried (Na2SO4), and the solvent removed in vacuo to yield the title compound. 1H NMR (CDCl3) δ 0.23 (s, 6 H), 1.01 (s, 9 H), 1.45 (s, 9 H), 2.16 (s, 3 H), 6.87 (s, 1 H), 7.49 (s, 1 H).
