実験手順

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 (Na2 SO4), 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).
