Reaction Steps

To 3-amino-5-(1-(3-benzoylphenyl)ethyl)-1,2,4-oxadiazole (0.60 g, 2.0 mmol) in pyridine (10 ml) was added methoxyamine hydrochloride (0.224 g, 2.7 mol). After reflux with stirring for 18 h, the mixture was poured upon ice water, extracted with ethylacetate. The extracts were washed with water, dried with anhydrous sodium sulfate, and evaporated under reduced pressure to a residue, which was chromatographed to afford 3-amino-5-(1-(3-(α-methoxyiminobenzyl)phenyl)ethyl)-1,2,4-oxadiazole (0.678 g, quantitive yield) as oily substance: NMR(CDCl3)δ 1.70(d, 3H), 3.97(s, 3H), 4.24(q, 1H), 4.48(broad singlet, 2H), 7.21-7.58(m, 9H) ppm; IR(neat) 3310, 3220, 1625, 1585, 1410, 1050 cm-1.
