Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 769965-95-9, name is 5′-Fluorospiro[cyclopropane-1,3′-indolin]-2′-one, A new synthetic method of this compound is introduced below., SDS of cas: 769965-95-9

Example 2.5Trans-2-chloro-N-{-4-((5′-fluoro-2′-oxospiro[cyclopropane-1 ,3′-indoline]-1 yl)methyl)cyctohexyl}-5-(trifluoromethyl)benzamide 5′-Fluorospiro[cyclopropane-1 ,3′-indolin]-2′-one (Intermediate H) {67 mg, 0.378 mmol) in dry D F (3 ml) was treated with NaH {60% in mineral oil) (15.12 mg, 0.378 mmol) under N2 and the contents left stirring for ~10 mins. After this time, trans- methanesulfonic acid 4-{2-chloro-5-trifluoromethyl-benzoylamino)-cyclohexyl methyl ester (Intermediate C) (105 mg, 0.253 mmol) was added and the solution heated to 70C for 2.5 h. After cooling to RT overnight, the mixture was diluted with EtOAc/H20 (40 ml) and transferred to a separating funnel. The organic layer was separated and washed with brine, dried (MgS04), and concentrated in vacuo to give a light brown oil. The crude oil was chromatographed on silica eluting with a gradient of 0%-30% EtOAc/iso-hexane follwed by an isocratic gradient of 30% EtOAc/iso-hexane to afford the title compound as a white solid; LC-MS Rt= 1.36 mins; [M+H]+ 495.3; Method = 2minl_C_30_v002. 1H NMR (400 MHz, CDCI3). delta 7.90 (1H, s), 7.55 (1 H, d), 7.50 (1H, d), 6.95 (1H, m), 6.80 (1 H, m), 6.60 (1H, m), 5.95 (1 H, d), 4.0 (1H, m), 3.65 (2H, d), 2.20 (2H, m), 1.85 (5H, m), 1.55 (2H, m), 1.25 (4H, m).
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
