Execute anonymous apex code in production

Hi,

I wanted to execute below code in 'Execute Anonymous' window in production every 5 minutes. I don't want to create Batch/Schedule classes at this time.

List<Queue_Member__c> qlistupd = new List<Queue_Member__c>();
for(Queue_Member__c q : [SELECT Id, Name, Last_Assigned_Case__c, Number_of_Open_Cases__c, Login_Status__c, Agent__c, Threshold__c, Chase_owner__c FROM Queue_Member__c]){
Integer count = [SELECT count() from case where status in ('Open', 'Action Required') and Ownerid = :q.Agent__c and RecordType.Name = 'TASQ OneSource'];
q.Number_of_Open_Cases__c = count;
qlistupd.add(q);
}

if(!qlistupd.isEmpty()){
try{
update qlistupd;
}
Catch(Exception e){
System.debug('Exception occured' + e);
}
}

Thanks
Kumar
