Science, 230-440 mesh) (13×4 cm column bed) using ethyl acetate as the eluent for the first 1.2 L and then with 5% ethanol in ethyl acetate. The fractions that contained homogeneous product were spin evaporated in vacuo to give a syrup. The pure 5-(4-ethylphenoxy)-4-(trans-4-hydroxycyclohexylamino)pyrimidine was converted to the hydrochloride by the same procedure described in Example 4. The residue was triturated under ethyl acetate to give a white solid which was collected, washed with ethyl acetate and dried in vacuo to give 1.25 g (77% yield) of 5-(4-ethylphenoxy)-4-(trans-4-hydroxycyclohexylamino)pyrimidine hydrochloride as a white solid, mp 245-243° C.
