Adding a certain compound to certain chemical reactions, such as: Thiomorpholine 1,1-dioxide, cas is 39093-93-1,the Thiomorpholine 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 39093-93-1,the Thiomorpholine, compound., 39093-93-1
Trifluoro-methanesulfonic acid 3-cyano-6,6-dimethyl-11-oxo-6,11-dihydro-5H-benzo[b]carbazol-8-yl ester (Compound B1, 30 mg, 0.069 mmol) was dissolved in 1,4-dioxane (1 mL), added with thiomorpholine 1,1-dioxide (19 mg, 2 eq.), Pd2 (dba)3 (6.3 mg, 0.1 eq.), BINAP (8.6 mg, 0.2 eq.) and K3PO4 (29 mg, 2 eq.), and stirred at 100¡ã C. overnight. The reaction solution was added to water, and then extracted with ethyl acetate. The organic layer was washed with saturated brine and dried over sodium sulfate. The drying agent was removed by filtration and the residues obtained after concentration under reduced pressure were purified by silica gel column chromatography (ethyl acetate/hexane) to obtain the target compound (white powder, 2.1 mg, 7percent). 1H-NMR (270 MHz, DMSO-d6) delta: 8. 29 (1H, d, J=8.6 Hz), 8. 07 (1H, d, J=8. 9 Hz), 8.00 (1H, s), 7. 55 (1H, dd, J=8. 5, 1. 7 Hz), 7. 34 (1H, d, J=2. 0 Hz), 7. 15 (1H, dd, J=9.1, 2.7 Hz), 4. 01 (4H, s), 3. 16 (4H, s), 1. 77 (6H, s).LCMS: m/z 420 [M+H]+
