Komponenten

Versuchsvorschrift

LiBH4 (0.48 mL, 0.96 mmol, 2 M in THF) was added to a stirred solution of ethyl[6-(1H-tetrazol-1-yl)pyridin-3-yl]acetate (0.150 g, 0.64 mmol) in THF (20 ml) at 0° C. The resulting solution was stirred for 12 h. Water (5 ml) was added, and the resulting solution was extracted with dichloromethane (2×50 ml). The combined organic layers were dried over MgSO4, filtered, and evaporated under reduced pressure to yield the product after flash chromatography (eluted with 10-50% ethyl acetate in hexanes) as a colorless oil. 1H NMR (500 MHz, CDCl3) δ 9.51 (s, 1H), 8.43 (br s, 1H), 8.01 (dd, J=2.7, J=2.7 Hz, 1H), 7.91 (dd, J=2.1, J=2.0 Hz, 1H), 3.99 (br s, 2H), 3.00 (t, J=6.1, J=6.2 Hz, 2H). LC-MS (IE, m/z): 164.1 [(M+1)+−28].
