YieldReaction ConditionsOperation in experiment
69% With potassium carbonate; In N,N-dimethyl-formamide; at 20℃; 2,4-Dichlorothieno[2,3-d]pyrimidine (1.01 g, 4.93 mmol),(2S,3S)-3-Aminobicyclo[2.2.2]octane-2-carboxylic acid ethyl ester hydrochloride(0.98 g, 4.93 mmol) was dissolved in DMF (20 mL)K2CO3 (1.70 g, 12.33 mmol) was added to the reaction solution.The resulting mixture was stirred at room temperature overnight.H2O (50 mL) was added to the reaction mixture to quench the reaction.The resulting mixture was extracted with ethyl acetate (50 mL×3).The combined organic phases were washed with saturated brine (150 mL×3).Dry over anhydrous sodium sulfate, filter, and concentrate the filtrate under reduced pressure.The residue obtained was subjected to silica gel column chromatography(Petroleum ether / ethyl acetate (v / v) = 5 / 1) purification,The title compound was obtained as a pale yellow solid(1.25g, 69percent).
69% With potassium carbonate; In N,N-dimethyl-formamide; at 20℃; To a solution of <strong>[18740-39-1]2,4-dichlorothieno[2,3-d]pyrimidine</strong> (1.01 g, 4.93 mmol),(2S,3S)-ethyl 3-aminobicyclo[2.2.2]octane-2-carboxylate hydrochloride (1.15 g, 4.93 mmol) inDMF (20 mL) was added K2C03 (1.36 g, 9.84 mmol). The mixture was stirred at rt overnight.H20 (50 mL) was added to quench the reaction, and the resulting mixture was extracted withEtOAc (50 mL x 3). The combined organic layers were washed with saturated brine (150 mL x3), dried over anhydrous Na2S04, filtered, and the filtrate was concentrated in vacuo. The residuewas purified by silica gel chromatograph (PE/EtOAc (v/v) = 511) to give the tilte compound as alight yellow solid ( 1.25 g, 69 percent ).MS (ESI, pos. ion) m/z: 366.00 [M+Ht;1H NMR (600 MHz, CDCh) 8 (ppm): 7.26 (d, J = 6.0 Hz, 1H), 7.16 (d, J = 5.8 Hz, 1H), 4.64 (t,J = 5.3 Hz, 1H), 4.25 (q, J = 7.1 Hz, 2H), 2.45 (d, J = 5.7 Hz, 1H), 2.03 (d, J = 2.4 Hz, 1H), 1.96(d, J = 2.7 Hz, 1H), 1.89- 1.82 (m, 1H), 1.75- 1.63 (m, 6H), 1.46 (m,1H), 1.28 (t, J = 7.1 Hz,4H).
