1-Methylimidazole → Ethyl 2-methyl-2-[6-(trifluoromethyl)pyridin-3-yl]cyclopropanecarboxylate

Participants

Reaction Steps

A toluene (2 ml) solution of 5-isopropenyl-2-(trifluoromethyl)pyridine (219 mg, 1.17 mmol), Co(TPP) (26 mg, 0.039 mmol) and 1-methyl-1H-imidazole (320 mg, 3.9 mmol), ethyl diazoacetate (208 mg, 1.8 mmol) were treated in the same procedure as described in Example 2H. The crude residue (201 mg, 63% yield of the title compound as a black oil) was used in a further reaction without purification.
