Reaction Steps

To a stirred solution of tert-butyl 3-(5-methylpyridin-2-yl)pyrrolidine-1-carboxylate (260 mg, 1.0 mmol) in dry CH2Cl2 (3 mL) was added TFA (2 mL, 20% in CH2Cl2) dropwise at 0° C. The reaction mixture was stirred at rt for 3 h. TLC showed the disappearance of starting material. The reaction mixture was concentrated under vacuum to afford crude 5-methyl-2-(pyrrolidin-3-yl)pyridine (170 mg, 96%), which was used for the next step without purification.
