실험 절차

Using the procedure described in example 29, step 2, ethyl 2-(tert-butoxy)-2-[2,5-dimethyl-4-(tetramethyl-1,3,2-dioxaborolan-2-yl)thiophen-3-yl]acetate (28f) (60 mg, 0,148 mmol) is converted, by reaction with 4-(trifluoromethyl)cyclohex-1-en-1-yl trifluoromethanesulfonate (41a) and after purification by preparative TLC (cyclohexane/ethyl acetate 90/10), to 2-(tert-butoxy)-2-{2,5-dimethyl-4-[4-(trifluoromethyl)cyclohex-1-en-1-yl]thiophen-3-yl}acetate (41b) (31 mg, 0.07 mmol, 50%).
