Reaction Steps

1M NaOH (2 mL) was added to a solution of 2-(6-tert-butoxycarbonylamino-pyridin-3-ylmethyl)-2-methyl-malonic acid tert-butyl ester ethyl ester (0.42g, 1.03 mmol) in THF/EtOH (4 mL, 1:1) . The reaction mixture was stirred at 50° C. for 16 h. CH2Cl2 was added and the mixture was washed with 0.5 M HCl and brine and dried. Concentration under reduced pressure gave 2-(6-tert-butoxycarbonylamino-pyridin-3-ylmethyl)-2-methyl-malonic acid mono-tert-butyl ester (348 mg, 89%).
