Reaction Steps

A solution of tert-butyl 3-(4-((4-((2-(2-methoxy-2-oxoethyl)phenyl)ethynyl)-5-(trifluoromethyl)pyrimidin-2-yl)amino)phenyl)pyrrolidine-1-carboxylate (I138) (0.527 g, 0.906 mmol) in EtOH (10 mL) was added to a solution of 10% Pd/C (0.500 g) in DMF (6 mL). The reaction was stirred at room temperature for 24 hours under an atmosphere of hydrogen. The reaction was filtered through a pad of celite and washed through with EtOAc (80 mL). The solvent was removed in vacuo to afford a yellow oil. This was taken up in DMF/EtOH (1:1, 10 mL) and a slurry of 10% Pd/C (0.500 g, 1 eq) in DMF was added. The reaction was stirred under an atmosphere of H2 at room temperature for an additional 24 hours. The reaction was filtered through a pad of celite and washed through with EtOAc (80 mL). The solvent removed in vacuo to afford a yellow oil which was purified by column chromatography on silica gel (0-45% EtOAc in petroleum benzine 40-60° C.) to yield the title compound (I139) (0.126 g, 24%) as a brown oil; 1H NMR (400 MHz, CDCl3) δ 8.54 (s, 1H), 7.58 (d, J=8.2 Hz, 2H), 7.39 (s, 1H), 7.30-7.17 (m, 6H), 3.91-3.72 (m, 2H), 3.75 (s, 2H), 3.68 (s, 3H), 3.66-3.52 (m, 1H), 3.47-3.21 (m, 3H), 3.17-3.04 (m, 4H), 2.23 (d, J=20.4 Hz, 1H), 1.97 (dd, J=21.1, 10.2 Hz, 1H), 1.48 (d, J=3.1 Hz, 9H). LCMS Method C: rt 6.91 min; m/z 585 [M+H], 607 [M+N]+.
