Embodiment 1
[2249] Example 1: (R)-3-[2-[3-(8-aminopyrido[3,4-d]pyrimidin-2-yl)phenyl]ethynyl]-3-hydroxy yl-1-methyl-pyrrolidin-2-one .
[2250]
[2251] A 500 mL round bottom flask was charged with a stir bar, 2-(3-iodophenyl)pyrido[3,4-d]pyrimidin-8-amine (15 g, 43 mmol), Pd(PPh 3 ) 2 Cl 2 (3.0g, 4.3mmol), CuI (0.9g, 4.3mmol), DIPEA (11g, 85mol), (R)-3-ethynyl-3-hydroxyl-1-methylpyrrolidin-2-one (14g, 99 mmol) and THF (300 mL). The resulting mixture was stirred at 60 °C for 2 h, then cooled to 20 °C. The product was isolated by filtration and purified by FCC to afford (R)-3-[2-[3-(8-aminopyrido[3,4-d]pyrimidin-2-yl)phenyl] as a light yellow solid Ethynyl]-3-hydroxy-1-methyl-pyrrolidin-2-one (9.0 g, 58%). MS (ESI): C 20 h 17 N 5 o 2 The mass calculated value is 359.14; m / z measured value is 360.1 [M+H] + . 1 H NMR (400MHz, DMSO-d 6 )δ9.53(s,1H),8.76–8.71(m,1H),8.70–8.67(m,1H),8.02(d,J=5.6Hz,1H),7.62–7.53(m,2H),7.45 (s,2H),7.04(d,J=5.6Hz,1H),6.50(s,1H),3.42–3.36(m,2H),2...
Embodiment 2
[2252] Example 2: (S)-3-[2-[3-(8-aminopyrido[3,4-d]pyrimidin-2-yl)phenyl]ethynyl]-3-hydroxy yl-1-methyl-pyrrolidin-2-one .
[2253]
[2254] The title compound was obtained using similar conditions as described in Example 1 and utilizing 2-(3-iodophenyl)pyrido[3,4-d]pyrimidin-8-amine and (S)-3-ethynyl-3-hydroxy -1-methylpyrrolidin-2-one to obtain (S)-3-[2-[3-(8-aminopyrido[3,4-d]pyrimidin-2-yl)phenyl]acetylene base]-3-hydroxy-1-methyl-pyrrolidin-2-one. MS (ESI): C 20 h 17 N 5 o 2 The mass calculated value is 359.14; m / z measured value is 360.1 [M+H] + . 1 H NMR (400MHz, DMSO-d 6 )δ9.53(s,1H),8.76–8.71(m,1H),8.70–8.67(m,1H),8.02(d,J=5.6Hz,1H),7.62–7.53(m,2H),7.45 (s,2H),7.04(d,J=5.6Hz,1H),6.50(s,1H),3.42–3.36(m,2H),2.83(s,3H),2.50–2.44(m,1H), 2.28–2.17(m,1H).
Embodiment 3
[2255] Example 3: (R)-3-[2-[3-(4-aminopyrido[3,2-d]pyrimidin-6-yl)-4-methyl-phenyl]acetylene Base] -3-hydroxy-1-methyl-pyrrolidin-2-one .
[2256]
[2257] A 20 mL microwave vial was charged with 6-chloropyrimido[3,2-d]pyrimidin-4-amine (75.0 mg, 0.42 mmol), (R)-3-hydroxy-1-methyl-3-((4- Methyl-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)ethynyl)pyrrolidin-2-one (148mg , 0.42mmol), K 3 PO 4 (264mg, 1.24mmol), 1,4-dioxane (5mL) and H 2 O (1 mL). The resulting mixture was aerated with argon for 5 min, and then treated with [1,1'-bis(di-tert-butylphosphino)ferrocene]palladium(II) dichloride (PdCl 2 (dtbpf)) (27.0 mg, 0.04 mmol) treatment. The mixture was aerated with argon for another 5 min, and the resulting mixture was subjected to microwave irradiation at 85 °C for 1 h, then it was cooled to RT. The resulting mixture was poured into water (30 mL), and extracted with ethyl acetate (30 mL×3). The combined organic extracts were subjected to anhydrous Na 2...
