Adding a certain compound to certain chemical reactions, such as: 35344-95-7, name is 1H-Pyrazole-4-carbaldehyde, belongs to pyrazoles-derivatives compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 35344-95-7, 35344-95-7<\/a><\/p>\n

lH-pyrazole-4-carbaldehyde (1.73 g, 18.00 mmol, 1.20 eq.) and Cs2C03 (9.78 g, 30.02 mmol, 2.00 eq.) were added to a solution of tert-butyl N-[3-(methanesulfonyloxy)cyclobutyl] carbamate (4 g, 15.08 mmol, 1.00 eq.) in DMF (100 mL). The resulting solution was stirred for 16 hours at 80 C and then diluted with 300 mL of water. The resulting solution was extracted with ethyl acetate (3×300 mL) and the organic layers combined. The resulting mixture was washed with brine (3×500 mL), dried over anhydrous sodium sulfate and concentrated under vacuum. The crude product was purified by Flash with the following conditions: Column, C18 silica gel; mobile phase, X:H20 Y_ACN=70\/30 increasing to X:H20 Y_ACN=20\/80 within 30 min; Detector, UV 254 nm. The isomers were separated by Prep-SFC with the following conditions (Prep SFC80-2): Column, Chiralpak IB, 2*25cm, 5um; mobile phase, CO2 (80%), IPA (20%); Detector, UV 220nm. This resulted in 1.2 g (30%) of tert-butyl N-trans-3-(4- formyl-lH-pyrazol-l-yl)cyclobutyl] carbamate as a white solid.<\/p>\n
