Works for me when spelled correctly:

regression=# insert into t2 (select int2(int4(b)) from t1 where a = 1);
INSERT 314647 1

If you make a suitable conversion function then you can omit the
explicit conversion:

regression=# create function int2(int8) returns int2 as
regression-# 'begin return int2(int4($1)); end;' language 'plpgsql';
regression=# insert into t2 (select b from t1 where a = 1);
INSERT 314649 1
