Reaction Steps

Reaction of the above carbamate (300 mg, 0.542 mmol) with an excess of TFA (2 mL) in CH2Cl2 (10 mL) at room temperature for 3 hrs, followed by treatment with aq. NH3 gave 4-[4-[2-(difluoromethyl)-4-methoxy-1H-benzimidazol-1-yl]-6-(4-morpholinyl)-1,3,5-triazin-2-yl]aniline (217 mg, 88%), which was used in the next step without further purification: 1H NMR (DMSO-d6) δ 8.17 (d, J=8.7 Hz, 2H), 8.05 (dd, J=8.3, 0.4 Hz, 1H), 7.80 (t, JHF=52.9 Hz, 1H), 7.47 (t, J=8.2 Hz, 1H), 6.99 (d, J=7.8 Hz, 1H), 6.68 (d, J=8.8 Hz, 2H), 6.05 (s, 2H), 4.01 (br s, 2H), 3.99 (s, 3H), 3.88 (br s, 2H), 3.75 (m, 4H).
