A balanced equation for a chemical reaction indicates what is reacting and what is produced, 1242156-59-7, but it reveals nothing about how the reaction actually takes place. The reaction mechanism is the process, or pathway, by which a reaction occurs.6-(tert-Butyl)-8-fluorophthalazin-1(2H)-one, cas is 1242156-59-7,the phthalazine compound. An updated downstream synthesis route of 1242156-59-7 as follows.
Step 5. Preparation of 2-(6-tert-butyl-8-fluoro-l-oxo-lH-phthalazin-2-yl)-4-iodo-pyridine-3- carbaldehyde Method A In a 1 L round-bottomed flask, 6-tert-butyl-8-fluorophthalazin-l(2H)-one (5.6 g, 25.4 mmol) was combined with THF (300 ml) to give a colorless solution. Sodium hydride (1.12 g, 28.0 mmol) was added. The reaction mixture was stirred at ambient temperature for 10 min. 2-Fluoro-4- iodonicotinaldehyde (7.02 g, 28.0 mmol) was added and the reaction mixture was stirred at ambient temperature for 1 h. The reaction was complete as determined by LCMS analysis. The reaction mixture was quenched with saturated NH4CI. The reaction mixture was poured into 200 mL of H20 and extracted thrice with CH2CI2. The organic layers were washed with brine, then dried over Na2S04 and concentrated under vacuum. The resultant bright yellow solid was transferred into a filter funnel and the flask washed twice with a small volume of EtOAc to ensure complete transfer of the solid into the funnel. The liquid was filtered through. The solid was triturated twice with Et20 and dried under vacuum to afford the desired product as a cream- colored solid (8.09 g, 17.9 mmol, 70.5 % yield). (M+H)+ = 452 m/e. *H NMR (400 MHz, CUC -d) delta ppm 1.44 (s, 9 H) 7.49 – 7.54 (m, 1 H) 7.54 (d, 7=1.77 Hz, 1 H) 8.03 (d, 7=5.31 Hz, 1 H) 8.30 (d, 7=2.53 Hz, 1 H) 8.37 (d, 7=5.31 Hz, 1 H) 9.98 (s, 1 H).
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 6-(tert-Butyl)-8-fluorophthalazin-1(2H)-one, 1242156-59-7
