select * from table
where dateadd(y, -1, getdate()) > datepurchased
and customer_no not in
(select distinct customer_no from table where datepurchased > dateadd(y, -1, getdate()) )

replace table with the table name.

I'd recommend a group by as it permits other useful metrics (such date of last purchase) and then filter the result via the having clause
SELECT
      customer_no
    , max(datepurchased)  AS last_purchase_dt
    , count(*)            AS num_purchases
FROM YourTable
GROUP BY
    customer_no
HAVING
    max(datepurchased) <= dateadd(YEAR, -1, getdate())
