A solution of [6-(3-aminomethyl-4-fluoro-phenyl)-2-methoxy-pyrimidin-4-yl]-[2-(4-methoxy-phenyl)-ethyl]-amine [200 mg, 0.52 mmol, see example 27] and triethylamine (264 mg, 2.61 mmol) in DCM (5 mL) is treated with methoxyacetyl chloride (114 mg, 1.1 mmol) at 0° C. After 15 hours at 4° C. in a refrigerator, the mixture is quenched with water (10 mL) filtered through Chem-Elut. The filtrate is concentrated, and subjected to chromatography on silica gel eluting with 10% MeOH in DCM to give N-(2-fluoro-5-{2-methoxy-6-[2-(4-methoxy-phenyl)-ethylamino]-pyrimidin-4-yl}-benzyl)-2-methoxy-acetamide, which is treated with saturated solution of hydrogen chloride in EtOAc followed by lyophilization to afford N-(2-Fluoro-5-{2-methoxy-6-[2-(4-methoxy-phenyl)-ethylamino]-pyrimidin-4-yl}-benzyl)-2-methoxy-acetamide hydrochloride [190 mg, 74%, Example 28]. LCMS: RT=2.35 minutes, MS: 455 (M+H). IC50=9 nM
