Participants

Reaction Steps

A solution of KOH (300 mg, 5.35 mmol) in EtOH (4 mL) was added to a solution of 2-(6-tert-butoxycarbonylamino-2-methyl-pyridin-3-ylmethyl)-malonic acid diethyl ester (1.85 g, 4.86 mmol) in EtOH/methylene chloride (2:1, 21 mL) at 0° C. The mixture was stirred for 40 h at room temperature and EtOAc was added. The mixture was washed with 0.5 M HCl and brine, dried and concentrated under reduced pressure to give crude 2-(6-tert-butoxycarbonylamino-2-methyl-pyridin-3-ylmethyl)-malonic acid monoethyl ester (1.45 g).
