Reaktionsschritte

Tris(1,1-dimethylethyl)2-(2,6-dichloro-5-fluoro-4-pyrimidinyl)-1,1,2-hydrazinetricarboxylate (1.413 g, 2.85 mmol) was dissolved in THF (5 mL). To this solution was added triethylamine (0.48 mL, 3.4438 mmol), followed by commercially available (3-thienylmethyl)amine (0.322 g, 2.85 mmol) which was dissolved in THF (1 mL). After stirring, the reaction mixture was diluted with water, and the aqueous layer was extracted with ethyl acetate. The organics were dried (Na2SO4) and concentrated to produce tris(1,1-dimethylethyl)2-{2-chloro-5-fluoro-6-[(3-thienylmethyl)amino]-4-pyrimidinyl}-1,1,2-hydrazinetricarboxylate as a white solid (1.6214 g, 99%). LCMS: (M+H−3Boc)+=374.1.
