Reaction Steps

Add sodium tetrahydroborate (146 mg, 3.7 mmol) to a solution of 5-(2-bromo-4-fluorophenyl)-3,4-dihydro-2H-pyrrole (420 mg, 1.73 mmol) in methanol-acetic acid (saturated; 10 mL) mixture at −40° C. After warming up to RT, add water (10 mL) and make the solution basic with a NaOH solution (2 N). Extract the solution with DCM, wash the organic solution with aqueous saturated sodium chloride, dry over potassium carbonate, and remove the organic solvent to give the title compound (300 mg, 71%). MS (ES) m/z 236 [M+1]+.
