Reaction Steps

A solution of HCl in 1,4-dioxane (4.0 M, 0.5 mL, 2 mmol) was added to 2-{3-[(2,2-difluoro-2-phenylethyl)amino]-6-chloro-2-fluorophenyl}-N-({6-[(tert-butoxy) carbonylamino]-2,4-dimethyl(3-pyridyl)}methyl) acetamide (18.5 mg, 32 μmol), as prepared in the preceding step. After stirring at ambient temperature for 3 hours, solid precipitated. A solution of MeOH (0.1 mL) in DCM (1 mL) was added to dissolve the solid. After stirring for another 2 hours the reaction was concentrated to give a brown solid, that was washed with ether and DCM and dried in vacuo to produce the title compound (12.6 mg, 77% yield) as a pale brown solid. 1H-NMR (400 MHz, CD3OD) δ 8.40 (bs, 1H),7.53-7.51 (m, 2H), 7.47-7.40 (m, 3H), 6.93 (dd, J=8.8, 1.3 Hz, 1H), 6.68 (s, 1H), 6.64 (t, J=9.1 Hz, 1H), 4.31 (d, J=4.6 Hz, 2H), 3.81 (t, J=13.8 Hz, 21H), 3.67 (d, J=1.2 Hz, 2H), 2.54 (s, 3H), 2.42 (s, 3H). Mass spectrum (LCMS, ESI) calc'd for C24H25ClF3N4O (M+H): 477.2. Found: 477.5.
