How to save an execute as a stored procedure so I can just run it

Hi:

I have a stored procedure that takes a number of parameters.  Rather than select the parameters each time, I'd just like to run it  - e.g. RunDefrag.

I tried to save as a stored procedure but go a grammar error.  

CREATE PROCEDURE [RunDefrag]
        EXECUTE dbo.dba_indexDefrag_sp
              @executeSQL           = 1
            , @printCommands        = 1
            , @debugMode            = 1
            , @printFragmentation   = 1
            , @forceRescan          = 1
            , @maxDopRestriction    = 1
            , @minPageCount         = 8
            , @maxPageCount         = NULL
            , @minFragmentation     = 1
            , @rebuildThreshold     = 30
            , @defragDelay          = '00:00:05'
            , @defragOrderColumn    = 'page_count'
            , @defragSortOrder      = 'DESC'
            , @excludeMaxPartition  = 1
            , @timeLimit            = NULL
            , @database             = 'testDB';

Any help in figuring how to do this would be greatly appreciated.
