You have to escape the percent sign in crontab with "\":

	run.  The entire command portion of the line, up to a newline
	or % character, will be executed by /bin/sh or by the shell
	specified in the SHELL variable of the cronfile.
	Percent-signs (%) in the command, unless escaped with
	backslash (\), will be changed into newline characters, and
	all data after the first % will be sent to the command as
	standard input.
