Token mismatch when inserting two columns in another mysql table?

I have a code that selects two columns in a database:

SELECT DISTINCT ('owner_account'), 'grouped_country'
FROM 'genuine_k_value';

What I have to do is insert values into another table. I have tried to do the following:

INSERT INTO 'genuine_agents' ( 'agent_email', 'agent_country' )
SELECT DISTINCT ('owner_account'), 'grouped_country'
FROM 'genuine_k_value';

But it gives me:

  

Error: Token mismatch

I know that the query has to be in a form:

INSERT INTO tabla (´columna1´, ´columna2´)
VALUES ('valor 1', 'valor 2');

But I can not apply it to my case.
