실험 절차

A solution of 2-(3-{6-[2-(2,4-dichloro-phenyl)-ethylamino]-2-methoxy-pyrimidin-4-yl}-phenyl)-2-methyl-propionic acid [100 mg, 0.218 mmol, Example 49(b)] in DCM (2 mL) is treated with HBTU (515.2 mg, 1.35 mmol). The mixture is stirred at room temperature for 2 hours and treated with 2-dimethylamino-ethanol (0.154 mL, 1.53 mmol). After stirring overnight, the mixture is quenched with water and extracted with ethyl acetate. The combined organic layers are washed with brine, dried over sodium sulfate and concentrated. The residue is subjected to silica gel chromatography eluting with 0 to 7.5% MeOH in DCM to obtain 2-(3-{6-[2-(2,4-dichloro-phenyl)-ethylamino]-2-methoxy-pyrimidin-4-yl}-phenyl)-2-methyl-propionic acid 2-dimethylamino-ethyl ester as an oil which is treated with 1M hydrogen chloride in ether affording 2-(3-{6-[2-(2,4-dichloro-phenyl)-ethylamino]-2-methoxy-pyrimidin-4-yl}-phenyl)-2-methyl-propionic acid 2-dimethylamino-ethyl ester dihydrochloride [88 mg, 67%, Example 51] as a solid. LC/MS: RT=2.1 minutes, MS: 531 (M+H). 1H NMR [300 MHz, (CD3)2SO]: □10.16 (1H, br s), 7.3-7.82 (7H, m), 6.62 (1H, s), 4.37 (2H, m), 3.96 (3H, s), 3.68 (2H, m), 3.32 (2H, m), 3 (2H, m), 2.63 (6H, s), 1.6 (6H, s).
