Coldfusion HMAC-SHA1 encryption

<cfset x1 = toString(tobase64(result))>

The other function is returning hex, not base64. Other than that it seems to work fine for me:

 <cfset x1 = binaryEncode(result, "hex")>

The clue is in your expected output string: it contains only digits and lowercase letters. If you look closer, all the letters are in the range a-f. Therefore it is extremely likely that it is a hexadecimal string.

The last line of your example code encodes the result as base64, not hexadecimal. You can encode the result as hexadecimal by changing the last line to this:

<cfset x1 = binaryEncode(result,"hex")>

I ran the modified code and got

9E734661C9E8B6DC9B6B4B3DEF9769C00E8843B8

which is the uppercase version of your expected string.
