As a common heterocyclic compound, it belongs to quinuclidine compound,Quinuclidine-4-carboxylic acid hydrochloride,40117-63-3,Molecular formula: C8H14ClNO243,mainly used in chemical industry, its synthesis route is as follows.,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]+
