React it with NaOH and then CaO and NaOH(decarboxylation) will give 
CH3CH3  then react it with dehydrogenate with KOH or K2O will give ethene 
then Br2 will give CH3CH2Br

React C2H5COOH with NaOH(decarboxylation), it will give C2H6, then add KOH to it to get C2H5, then add Br2 to it(bromination) to get C2H5Br
