Electric Literature of 39806-90-1<\/a>, In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 39806-90-1 as follows.<\/p>\n

Example 58. Synthesis of (R)-5-(l,4-dimethyl-6-(l-methyl-lH-pyrazol-4-yl)-5,6- dihydro-4H-benzo[b] [l,2,4]triazolo[4,3-d][l,4]diazepin-8-yl)pyridin-2-amine (Compound 76). The title compound was synthesized by the following scheme:[00393] (R)-8-bromo-l,4-dimethyl-6-(l-methyl-lH-pyrazol-4-yl)-5,6-dihydro-4H-benzo[b] [l,2,4]triazolo[4,3-d][l,4]diazepine (Step 1). A mixture of (R)-8-bromo-l,4-dimethyl-5,6- dihydro-4H-benzo[b][l,2,4]triazolo[4,3-d][l,4]diazepine (292 mg, 1 mmol), 4-iodo-l-methyl- lH-pyrazole (312 mg, 1.5 mmol), copper (I) iodide (58 mg, 0.3 mmol), 1,10-phenanthroline (54 mg, 0.3 mmol) and potassium phosphate (424 mg, 2 mmol) in dimethyl sulfoxide (10 mL) was heated at 150C for 14 hours under nitrogen. The reaction mixture was diluted with ethyl acetate (20 mL) and washed with brine (20 mL x 3). The organic phase was dried over anhydrous sodium sulfate and then filtered. The filtrate was concentrated to give (R)-8-bromo-l,4-dimethyl- 6-(l-methyl-lH-pyrazol-4-yl)-5,6-dihydro-4H-benzo[b] [1,2,4] triazolo[4,3-d][l,4]diazepine which was used in the next step without further purification. LRMS (M+H)+: calcd 372.07; found 372.<\/p>\n

According to the analysis of related databases, 39806-90-1, the application of this compound in the production field has become more and more popular.<\/p>\n
