実験手順
Methyl 2-(2-(2-(2-((2-methyl-4-(piperidin-4-yl)phenyl)amino)-5-(trifluoromethyl)pyrimidin-4-yl)ethyl)phenyl)acetate (54) (1.10 g, 2.15 mmol) was dissolved in dry MeOH (20 mL) and formaldehyde solution (37% aq; 348 μL, 4.29 mmol) was added. Sodium triacetoxyborohydride (2.27 g, 10.7 mmol) was added under nitrogen and the resultant mixture was stirred at room temperature for 16 hours. Ethyl acetate (50 mL) was added and the mixture was washed with 10% NaHCO3 solution (20 mL). The organic layer was separated, dried (MgSO4) then the volatiles removed by evaporation under reduced pressure. Chromatography (SiO2, 0-50% MeOH/DCM) gave the title compound (I55) (480 mg, 42%) as a cream solid; 1H NMR (400 MHz, CDCl3) δ 8.54 (s, 1H), 7.83-7.73 (m, 1H), 7.35 (s, 1H), 7.32-7.19 (m, 3H), 7.19-7.09 (m, 2H), 7.07-6.97 (m, 1H), 3.76 (s, 2H), 3.70 (s, 3H), 3.23 (d, J=11.5 Hz, 2H), 3.17-3.04 (m, 4H), 2.61-2.51 (m, 1H), 2.50 (s, 3H), 2.35 (s, 3H), 2.33-2.24 (m, 2H), 2.02-1.84 (m, 4H). LCMS Method C: rt 5.25 min; m/z 527.2 [M+1]+.
