실험 절차

To a solution of the product prepared in Step A (704 mg, 1.9 mmol, 1 eq) in methanol (10 mL) was added a solution of NaOMe in MeOH (2.46 mL of a 25% solution, 10.6 mmol, 5.6 eq). After 1 hr, 1 N HCl was added, the aqueous was extracted with diethyl ether, washed with brine, dried over MgSO4 and concentrated to yield methyl 3-(trifluoromethyl)-1H-pyrrole-2-carboxylate.
