SQL 2012 Always On Availability Create Key for Dynamics CRM syntax

Question

Hi I am trying to follow this terribly written article to setup CRM to be part of a SQL alwayson availability group.  
The part that is pissing me off is the create SQL logins.  http://technet.microsoft.com/en-us/library/jj822357.aspx#BKMK_always_updateorg
So many errors with this post causing so much frustration.  What is the actual correct Syntax for creating the key?
Obviously you have to use a UNC path to the CRM front end server.  SQL doesnt like UNC and I think an earlier guy said it doesnt like double quotes.  Here is what I have and it does not like it.  Its hard to see but right before end I have two
single quotes to close it.  It's complaining about the \\ in the UNC path.  
IF NOT EXISTS (SELECT * FROM sys.asymmetric_keys WHERE name = 'MSCRMSqlClrKey') BEGIN EXECUTE ('CREATE ASYMMETRIC KEY MSCRMSqlClrKey FROM EXECUTABLE FILE ='\\CRM2013\C$\Program Files\Microsoft Dynamics CRM\tools\Microsoft.Crm.SqlClr.Helper.dll'')END

Answer 1

I finally got it working not by using the syntax in that article though.  First I did the select all from to see if the key existed by itself  
SELECT * FROM sys.asymmetric_keys WHERE name = 'MSCRMSqlClrKey'
NO key was there so then I did 
CREATE ASYMMETRIC KEY MSCRMSqlClrKey FROM EXECUTABLE FILE ='C:\Program Files\Microsoft Dynamics CRM\tools\Microsoft.Crm.SqlClr.Helper.dll'
