실험 절차

Triphenylphosphine polymer bound (Fluka, cat #93094) (1.6 g/mol, 6.3 mmol) was added to an aqueous (378 μL, 21.0 mmol)/THF (10 mL) solution of 3-[4-(azidomethyl)phenyl]-3-(trifluoromethyl)-3H-diazirine (506 mg, 2.1 mmol). The mixture was shaken until the starting material was no longer evident by TLC analysis (18 h). The triphenylphosphine-based support was filtered, washed with CH2Cl2, and the filtrate was concentrated in vacuum to obtain 350 mg (80%) of a yellow oil corresponding to the free amine: 1H NMR (CDCl3) δ 1.35-1.50 (br s, NH2), 3.89 (s, CH2), 7.17 (d, J=8.2 Hz, 2 C6H4), 7.35 (d, J=8.2 Hz, 2 C6H4); 13C NMR (CDCl3): δ 28.4 (q, J=39.9 Hz, C diazirine), 45.9 (CH2NH2), 122.2 (q, J=273.2 Hz, CF3), 126.7 (C6H2), 127.5 (C6H2), 145.0 (C6H2) (one peak is overlapped with an other one).
