Abstract: Nitration, benzylation followed by bromination of 4- hydroxy­acetophenone is described to obtain nitrobenzyloxy­phenacyl bromide derivative 3. Sodiumborohydride reduction of 3 gives rise to the diol 6. Reaction of 6 with Ph3P/I2/imidazole yields sty­rene derivative 7. Compound 7 on selective reduction of the nitro group followed by N-formylation and epoxidation affords the key intermediate N-[2-benzyloxy-5-(2-oxiranyl)­phenyl]­formamide 4.
