Laravel 5 using havingRaw on relationship's column alias

I need to grab the vehicles whose relation 'dealer' is having distance < 200

Vehicle::join('dealers', 'vehicles.dealer_id', '=', 'dealers.id')
     ->select(DB::raw("dealers.id, ( cos( radians(latitude) ) * cos( radians( longitude ) ) ) AS distance"))
     ->havingRaw('distance < 200');

I am trying to use havingRaw on the alias 'distance' from the relation (belongsTo) dealer. But failed with an error:

Column not found: 1054 Unknown column 'distance' in 'having clause'
