Versuchsvorschrift

To a solution of racemic ethyl 3-(5-cyano-3-fluoro-6-(5-fluoro-1-tosyl-1H-pyrrolo[2,3-b]pyridin-3-yl)pyridin-2-ylamino)-3-(1-methylcyclopentyl)propanoate, 144a, (0.150 g, 0.247 mmol) in THF (20 mL) was added sodium methoxide (0.053 mL of 25% wt solution in MeOH, 0.247 mmol). The reaction mixture was stirred at room temperature for 5 minutes. The reaction mixture was diluted with aqueous saturated NaHCO3 solution and EtOAc. The organic phase was dried over MgSO4, filtered and concentrated in vacuo. The product was purified by silica gel chromatography (40% EtOAc/Hexanes) to afford 90 mg of the desired product as a mixture of ethyl and methyl esters. The mixture was taken onto the next step without further purification: 1H NMR (400 MHz, CDCl3) δ 10.18 (s, 1H), 8.65 (dd, J=9.6, 2.5 Hz, 1H), 8.48 (d, J=2.8 Hz, 1H), 8.32 (s, 1H), 7.37 (t, J=14.1 Hz, 1H), 5.38 (d, J=7.9 Hz, 1H), 5.02 (td, J=9.8, 3.5 Hz, 1H), 3.54 (s, 3H), 2.80 (dt, J=15.8, 7.9 Hz, 1H), 2.57 (dd, J=14.9, 9.8 Hz, 1H), 1.80-1.57 (m, 7H), 1.43 (ddd, J=24.5, 14.1, 6.0 Hz, 3H), 1.08 (s, 3H); LCMS Gradient 10-90%, 0.1% formic acid, 5 minutes, C18/ACN, Retention Time=3.60 minutes (M+H) 440.26.
