Attempting to run Drush command from Ultimate Cron failing

From within a custom JSON migration module I'm trying to run the following

function migrate_source_example_json_cron() {
  /usr/local/bin/drush --root=/code --uri=example.com migrate-import --all --update
}

With the //Do some stuff line in there its showing up correctly in Ultimate Cron.

Obviously, I'm not using example.com :).

Enabling the module immediately fails when it gets to the first /.

Parse error: syntax error, unexpected '/' in /code/modules/migrate_source_example/modules/migrate_source_example_json/migrate_source_example_json.module on line 32 Call Stack: 0.0030 254616 1. {main}() /code/index.php:0 0.0045 552560 2.

Basically, I'm trying to access drush locally, set the root of the drupal site, and run the command migrate-import --all --update once an hour. All of the info has been taken directly from the drush status so it should all resolve locally.

Thanks for any help you can provide.

Best,
Shawn
