Probably you can't. Anyway , the Indian Government gave relaxation to people who are not in india for that period. If you are on of them, then you can change the money in selected branches of RBI (you have to come to india). But you should provide the passport as a proof that you are not visited here in that period(Nov 8 to Dec 30).

There are branches of some major Indian banks in Singapore, try going there and talk to the manager/staff about this issue. They might be able to help or give you some information.
