Procedure

2-(2-(2-(2-((4-(4-(tert-Butoxycarbonyl)morpholin-2-yl)phenyl)amino)-5-(trifluoromethyl)pyrimidin-4-yl)ethyl)phenyl)acetic acid (I90) (39 mg, 0.066 mmol) was dissolved in DMF (3 mL) and ammonium carbonate (38 mg, 0.40 mmol), HATU (28 mg, 0.073 mmol) and DIPEA (0.046 mL, 0.27 mmol) were added. The yellow mixture was stirred at room temperature for 18 hours then added to water (30 mL) and brine (10 mL). The mixture was extracted with ethyl acetate (3×30 mL), and the combined ethyl acetate phases washed with brine (50 mL), dried over sodium sulfate and evaporated. The residue was chromotographed (4 g deactivated* silica cartridge, 0-100% 1% isopropylamine in ethyl acetate/petroleum benzine 40-60° C.) to give the title compound (I91) (23.3 mg, 60% yield) as a colourless glass; 1H NMR (400 MHz, CDCl3) δ 8.53 (s, 1H), 7.78 (s, 1H), 7.61 (d, J=8.4 Hz, 2H), 7.37 (d, J=8.5 Hz, 2H), 7.31-7.19 (m, 5H, overlaps with CHCl3), 5.58 (s, 1H), 5.42 (s, 1H), 4.40 (d, J=8.5 Hz, 1H), 4.08-3.84 (m, 3H), 3.74-3.63 (m, 3H), 3.16-3.00 (m, 5H), 2.85 (s, 1H), 1.48 (s, 9H). LCMS Method C: rt 6.29 min; m/z 586.1 [M+H]+, 530.1 [M−tBu+2H]+, 608.1 [M+Na]+; m/z 584.1 [M−H]−.
