实验步骤: To a solution of N-methyl-L-proline monohydrate (0.26 g, 1.79 mmol) and benzotriazole-1-yl-oxy-tris-pyrrolidinophosphonium hexafluorophosphate (1.4 g, 2.69 mmol) in anhydrous dichloromethane (3.0 ml) at 25° C. is added diisopropylethylamine (0.63 ml, 3.62 mmol) under an inert atmosphere. To this solution is added a solution of ethyl (2E,4S)-2,5-dimethyl-4-[methyl(3-methyl-L-valyl)amino]hex-2-enoate (0.39 g, 1.27 mmol, WO 99/32509) in anhydrous dichloromethane (2.0 ml). The resulting reaction mixture is stirred at room temperature overnight. The reaction mixture is evaporated in vacuo. The residue (300 mg, 0.78 mmol) is dissolved in methanol (6.85 ml), water (1.8 ml) and tetrahydrofuran (3.25 ml). To this reaction mixture is added aqueous lithium hydroxide solution (3.54 ml, 3.54 mol) The resulting mixture is stirred at room temperature overnight. The reaction mixture is diluted with dichloromethane/water. The organic layer is washed with citric acid, brine, dried over sodium sulfate and filtered. The solvent is removed in vacuo, and the residue is chromatographed by HPLC (0.01% trifluoroacetic acid in water/acetonitrile) to give the product as a yellow oil, 0.08 g (28% yield). MS: m/z 396.28 (M+1) The resulting reaction mixture The reaction mixture is evaporated in vacuo is stirred at room temperature overnight The organic layer is washed with citric acid, brine dried over sodium sulfate filtered The solvent is removed in vacuo the residue is chromatographed by HPLC (0.01% trifluoroacetic acid in water/acetonitrile)

实验步骤: A suspension of (S)-1-methylpyrrolidine-2-carboxylic acid monohydrate (14 mg, 0.11 mmol), PyBOP® (57 mg, 0.11 mmol), DIEA (49 μL, 0.28 mmol) in CH2Cl2 (0.5 mL) was stirred at RT for 10-15 minutes. This solution of activated acid was added to a suspension of tert-butyl 5-(2-(3-aminophenyl)quinazolin-4-ylamino)-1H-indazole-1-carboxylate (100 mg, 0.22 mmol) and CH2Cl2 (1 mL). The reaction mixture was stirred at RT for 1.5 h. Activated another 0.5 equivalent of the acid as described above and it was once again added to the reaction mixture. Stirred for 16 h, diluted with more CH2Cl2 and extracted with H2O (3×). Organic layer was dried under Na2SO4 and concentrated in vacuo to give the desired oil product tert-butyl 5-(2-(3-((S)-1-methylpyrrolidine-2-carboxamido)phenyl)-quinazolin-4-ylamino)-1H-indazole-1-carboxylate.
