Hydrochloric Acid → 3-{6-[2-(2,4-Dichloro-phenyl)-ethylamino]-2-methoxy-pyrimidin-4-yl}-benzoic acid hydrochloride

Participants

Reaction Steps

A suspension of 3-{6-[2-(2,4-dichloro-phenyl)-ethylamino]-2-methoxy-pyrimidin-4-yl}-benzoic acid [0.2 g, Example 35(w)] in DCM and MeOH is treated with a saturated solution of hydrogen chloride in EtOAc (0.5 mL), and chromatographed on silica gel eluting with 10% MeOH in DCM to provide the product, which is dissolved in acetonitrile/water/hydrochloric acid, and lyophilized to give 3-{6-[2-(2,4-dichloro-phenyl)-ethylamino]-2-methoxy-pyrimidin-4-yl}-benzoic acid hydrochloride [172 mg, Example 15(b)] as a solid. LCMS: RT=2.72 minutes, MS: 417 (M+H).
