Versuchsvorschrift
In like manner to the preparation of 5-[(4-aminophenoxy)methyl]-3-phenyl-1,2,4-oxadiazole, 5-(4-nitrophenoxymethyl)-3-methyl-1,2,4-oxadiazole was reacted with aqueous solution of sodium hydrosulfite and K2CO3 to prepare 5-[(4-aminophenox)ymethyl]-3-methyl-1,2,4-oxadiazole. 1H NMR (CDCl3): δ 6.82 (d, 2H, J=8.8 Hz), 6.63 (d, 2H, J=8.8 Hz), 5.15 (s, 2H), 3.38 (br s, 2H), 2.41 (s, 3H).
