実験手順

Dissolve 4-[4-(1,5-dimethyl-1H-pyrazol-4-ylmethyl)-3,4,5,6-tetrahydro-2H-[1,2′]bipyrazinyl-3′-yl]-benzylamine (0.2 g, 0.53 mmol) in methylene chloride (5 mL). Add methoxy-acetyl chloride (1 eq., 0.058 g, 0.53 mmol). Add polymer bounded morpholine (1.1 eq., 0.234 g, 0.58 mmol). Stir at room temperature for 3 hr. Purify by SCX followed by reverse phase chromatography to give free base N-{4-[4-(1,5-dimethyl-1H-pyrazol-4-ylmethyl)-3,4,5,6-tetrahydro-2H-[1,2′]bipyrazinyl-3′-yl]-benzyl}-2-methoxy-acetamide, (0.051 g, 21%). MS (ES): m/z=450.3 [M+H].
