実験手順

A mixture of [2-amino-5-(2,4-dichloro-phenyl)-pyridin-4-ylmethyl]-carbamic acid tert-butyl ester (1.78 g, 4.82 mmol, prepared according to Example 6, Step 3.2), tBuONO (1.05 mL, 8.0 mmol), and CuCl2 (1.01 g, 7.51 mmol) in CHCl3 (6 mL) was stirred at RT for 3 days with exclusion of light. The reaction mixture was concentrated under vacuum, then the remaining residue was suspended in a 2.0 M aqueous Na2CO3 solution (200 mL) and extracted with AcOEt (2×100 mL). The combined organic fractions were dried over Na2SO4, filtered, and evaporated. The residue was purified by Combi-Flash Companion™ (Isco Inc.) column chromatography (SiO2; gradient elution, [hexane/DCM 1:1]/TBME 95:5→4:6) to yield the title compound (1.17 g, 3.0 mmol, 62%) as a colorless solid. MS: 388 [M+1]+; HPLC: AtRet=2.89; TLC: RF 0.36 ([hexane/DCM 1:1]/TBME 95:5).
