2-Fluoro-5-(trifluoromethyl)phenyl isocyanate → HCID 10305478, compound

Participants

Reaction Steps

To a solution of 2-[3-(4-amino-phenyl)-1-methyl-1H-pyrazolo[3,4-d]pyrimidin-6-ylamino)-ethanol (25.4 mg, 0.1 mmol) in N-methylpyrrolidinine (0.5 mL) was added 2-fluoro-5-trifluoromethyl-phenyl isocyanate (22 mg, 0.11 mmol, 2.1 eq). The reaction mixture was stirred for 1 hour at room temperature while monitored by TLC. The mixture was then evaporated and the crude product was purified by preparative HPLC to give pure (2-fluoro-5-trifluoromethyl-phenyl)-carbamic acid 2-(3-{4-[3-(2-fluoro-5-trifluoromethyl-phenyl)-ureido]-phenyl}-1-methyl-1H-pyrazolo[3,4-d]pyrimidin-6-ylamino)-ethyl ester; 1H-NMR (DMSO): δ 3.71 (m, 2H), 3.81 (s, 3H), 4.34 (m, 2H), 7.41–7.60 (m, 4H), 7.92 (d, 2H, J=8.4 Hz), 8.11 (br s, 1H), 8.63 (s, 1H), 8.94 (s, 1 H), 9.15 (s, 1H), 9.36 (br s, 1H), 9.75 (br s, 1H); LC/MS (m/e)=695.2 (MH+).
