tert-Butyl 2-[4-(5-chloro-2-cyanophenyl)-5-methoxy-2-oxopyridin-1(2H)-yl]-3-(3-methyl-1,2-oxazol-5-yl)propanoate (Racemate) To a solution of 900 mg (2.4 mmol) of tert-butyl [4-(5-chloro-2-cyanophenyl)-5-methoxy-2-oxopyridin-1(2H)-yl]acetate in 18 ml of THF under argon at -70 C. were added 3.0 ml (3 0 mmol, 1.25 eq.) of 1 N lithium bis(trimethylsilyl)amide in THF, and the mixture was stirred for 30 min. Subsequently, 623 mg (3.4 mmol, 1.4 eq.) of 5-(bromomethyl)-3-methyl-1,2-oxazole were added, the mixture was stirred at -70 C. for 30 min and then stirred while coming to RT for 90 min. To the reaction mixture were added 15 ml of saturated aqueous ammonium chloride solution, 15 ml of water and 150 ml of ethyl acetate. The aqueous phase was extracted once with ethyl acetate, and the combined organic phases were washed with saturated aqueous sodium chloride solution, then dried and concentrated. The crude product was purified by means of Biotage-Isolera (eluent: cyclohexane/ethyl acetate, 0-38%). Yield: 1.10 g (95% of theory). LC/MS [Method 1]: Rt=1.04 min; MS (ESIpos): m/z=470 (M+H)+, 1H-NMR (400 MHz, DMSO-d6): delta [ppm]=8.03-7.93 (m, 1H), 7.76-7.67 (m, 2H), 7.37 (s, 1H), 6.50 (s, 1H), 6.05 (s, 1H), 5.36 (dd, 1H), 3.72-3.51 (m, 5H), 2.14 (s, 3H), 1.40 (s, 9H), 36958-61-9
As the paragraph descriping shows that 36958-61-9 is playing an increasingly important role.
