Embodiment 1

[0163] Example 1: (R)-N-((S)-1-(3-chlorophenyl)-2-hydroxyethyl)-2-(2-(5-methyl-2-((1-methyl Base-1H-pyrazol-5-yl)amino)pyridin-4-yl)-4-oxo-6,7-dihydrofuro[3,2-c]pyridin-5(4H)-yl)propionamide

[0164]

[0165] The first step: (4-chloro-5-methylpyridin-2-yl) (1-methyl-1H-pyrazol-5-yl) tert-butyl carbamate (5g, 15.5mmol), pinacol Borate (15.8g, 62.1mmol) was dissolved in dimethyl sulfoxide DMSO (50mL), and Pd-XPhos-G2 (1.2g, 1.5mmol), 2-dicyclohexylphosphine-2',4' were added under nitrogen protection , 6'-triisopropylbiphenyl XPhos (1.4g, 3.0mmol) and potassium acetate (3g, 31mmol), heated to 75 degrees overnight. The solution was cooled to room temperature, filtered, and the residue was purified by column chromatography to obtain (2-((tert-butoxycarbonyl)(1-methyl-1H-pyrazol-5-yl)amino)-5-methylpyridine-4 -yl) pinacol borate (2 g, white solid). LC-MS:ESI[M+H] + = 415.3.

[0166] The second step: (2-((tert-butoxycarbonyl)(1-methyl-1H-pyrazol-5-yl)amino)-5-methylpyridin-4-...

Embodiment 2

[0169] Example 2: (R)-N-((6-(dimethylamino)pyridin-2-yl)methyl)-2-(2-(5-methyl-2-((1-methyl- 1H-pyrazol-5-yl)amino)pyridin-4-yl)-4-oxo-6,7-dihydrofuro[3,2-c]pyridin-5(4H)-yl)propionamide

[0170] It was synthesized by the same method as in Example 1, LC-MS: ESI (M+H) 529.4. 1 H-NMR (DMSO-d6, 400MHz) 8.76(s, 1H), 8.33-8.37(m, 1H), 8.04(s, 1H), 7.44(t, J=7.6Hz, 1H), 7.31(d, J =5.6Hz,1H),7.13(s,1H),7.07(s,1H),6.46(t,J=8.4Hz,2H),6.24(s,1H),5.14-5.19(m,1H),4.21 (d,J=6.0Hz,2H),3.63-3.70(m,5H),3.00-3.10(m,2H),2.98(s,6H),2.38(s,3H),1.37(d,J=7.2 Hz, 3H).

Embodiment 3

[0171] Example 3: (R)-N-((6-(dimethylamino)pyridin-2-yl)methyl)-2-(2-(2-((1-methyl-1H-pyrazole- 5-yl)amino)pyridin-4-yl)-4-oxo-6,7-dihydrofuro[3,2-c]pyridin-5(4H)-yl)propionamide

[0172] Synthesized by the same method as in Example 1, LC-MS: ESI (M+H) 515.5. 1 H-NMR (DMSO-d6, 400MHz) 9.52(br s, 1H), 8.63(t, J=5.6Hz, 1H), 8.12(d, J=6.0Hz, 1H), 7.82(t, J=8.0Hz ,1H),7.61(s,1H),7.47(d,J=2.0Hz,1H),7.29(d,J=5.6Hz,1H),7.13(s,1H),6.98(d,J=8.4Hz ,1H),6.67(d,J=7.2Hz,1H),6.34(d,J=2.0Hz,1H),5.07-5.09(m,1H),4.38-4.40(m,2H),3.68-3.71( m, 5H), 3.18 (s, 6H), 3.12 (t, J=7.2Hz, 2H), 1.38 (d, J=7.2Hz, 3H).

Description

technical field [0001] The invention belongs to the field of medicinal chemistry, and specifically relates to a class of furolactam compounds, a preparation method and application. Background technique [0002] Extracellular signal-regulated kinases (ERKs) are a class of serine / threonine protein kinases discovered in the 1990s and are one of the important subfamilies of the MAPKs family of mitogen-activated protein kinases. Activated ERK can transmit extracellular signals to the nucleus, promote the phosphorylation of cytoplasmic target proteins or regulate the activity of other protein kinases, thereby regulating gene expression. Ras-Raf-MEK-ERK signal transduction is the center of the signaling network involved in regulating cell growth, development and differentiation, so ERK has various biological effects such as regulating cell proliferation, differentiation, migration, invasion and apoptosis. [0003] The Ras / Raf / MEK / ERK pathway is the main signaling pathway related t...
