It is shown that the quantization of the chiral Schwinger model in the Batalin-Vilkovisky framework can be carried out in an extended space of fields and antifields, where the master equation has a local solution. The Wess-Zumino term is generated in this way, avoiding the use of nonlocal expressions. The nilpotency of the new BRST charge is proven explicitly.
