Versuchsvorschrift

A solution of 2.5 ml of borane-methyl sulfide complex in 2M solution in tetrahydrofuran, 920 mg of 3-(3-phenyl-1,2,4-oxadiazol 5-yl)-propanoic acid (prepared by SRIRASTAVA et al., J. Heterocycl. Chem., Vol. 21, p. 1193 (1984) and 20 ml of tetrahydrofuran was stirred for one hour at ambient temperature. 10 ml of methanol were added over 5 minutes and evaporation to dryness under reduced pressure was carried out. The residue was chromatographed on silica (eluant: ethyl acetate - hexane (6-4)) to obtain 485 mg of the expected product.
