Reaction Steps

To a stirred solution of 6-tert-butoxycarbonylamino-nicotinic acid ethyl ester (3.50 g, 13.1 mmol) in THF (20 mL) under nitrogen was added LiAlH4 (0.91 g, 24.0 mmol) in THF (20 mL) over a period of 2 h. The reaction mixture was stirred for 6 h, then NH4Cl (sat.) was added (carefully) until neutral solution. The mixture was filtered and concentrated under reduced pressure to give (5-hydroxymethyl-pyridin-2-yl)-carbamic acid tert-butyl ester (2.00 g 68%).
