反応手順

4-Methoxyphenyl isocyanate (85 mg, 0.567 mmol) was added to a solution of tert-butyl 3-((pyridin-3-ylamino)methyl)piperazine-1-carboxylate (166 mg, 0.567 mmol) in CH2Cl2 (4 mL). After 1 h, the reaction mixture was concentrated under reduced pressure, and the material was purified by HPLC (10 to 90% MeCN/0.1% TFA in H2O/0.1% TFA gradient). This gave 81.7 mg (26%) of the TFA salt of the title compound as a white solid. LC-MS: RT=5.29 min, [M+H]+=442.2.
