Procedure

A suspension of 1.7 g. of 2',6'-bis(allyloxy)-4'-[(methylsulfonyl)-acetyl]acetanilide in 20 ml. of ethanol and 20 ml. of water was treated with a solution of 0.40 g. of sodium borohydride in 5 ml. of water. There was also added 0.1 g. of sodium hydroxide. The mixture was stirred for 3 hours at room temperature and evaporated to dryness. The residue was taken up in water, removed by filtration under vacuum, dried and recrystallized from ethyl acetate/petroleum ether, whereby there was obtained 2',6'-bis(allyloxy)-4'-[1-hydroxy-2-(methylsulfonyl)-ethyl]-acetanilide having a melting point of 162° C.
