How to prepare butane by decarboxylation method?

How to prepare butane by decarboxylation method?

Butane can be prepared from decarboxylation method from pentanoic acid. Pentanoic acid is a carboxylic acid . In carboxylation reaction, one carbon atom in the carboxylic acid is removed to give the alkane as the product. Butane has four carbon atoms. Therefore we have to use a carboxylic acid which have five carbon atoms.
