Regex on Chrome pattern input validation

I have an RFC 5322 compliant email regex pattern to validate my input. This works in all browsers, but Chrome show me the following error on console:

Pattern attribute value ^[-a-z0-9~!$%^&*_=+}
{\'?]+(\.[-a-z0-9~!$%^&*_=+}{\'?]+)*@([a-z0-9_]
[-a-z0-9_]*(\.[-a-z0-9_]+)*\.(aero|arpa|biz
|com|coop|edu|gov|info|int|mil|museum|name
|net|org|pro|travel|mobi|[a-z][a-z])|([0-9]
{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}))
(:[0-9]{1,5})?$
is not a valid regular expression:

Uncaught SyntaxError: Invalid regular expression:
/^[-a-z0-9~!$%^&*_=+}{\'?]+(\.[-a-z0-9~!$%^
&*_=+}{\'?]+)*@([a-z0-9_][-a-z0-9_]*(\.[-a-z
0-9_]+)*\.(aero|arpa|biz|com|coop|edu|gov

|mobi|[a-z][a-z])|([0-9]{1,3}\.[0-9]{1,3}\.
[0-9]{1,3}\.[0-9]{1,3}))(:[0-9]{1,5})?$/

Invalid escape

I just can't find what chunk have this invalid escape.
