39093-93-1, A common heterocyclic compound, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route., 39093-93-1

Step-E: (1R,2R)?N-(1-Cyanocyclopropyl)-2-{4-[4-(1,1-dioxo-1lambda6-thiomorpholin-4-yl)phenyl]-2-(4-fluorophenyl)-1,3-oxazol-5-yl}cyclohexanecarboxamide (Compound 7) [0274] To a mixture of (1R,2R)-2-(4-(4-bromophenyl)-2-(4-fluorophenyl)oxazol-5-yl)-N-(1-cyanocyclopropyl)cyclohexanecarboxamide (116 mg, 0.228 mmol), thiomorpholine 1,1-dioxide (93 mg, 0.685 mmol), Chloro(2-dicyclohexylphosphino-2?,4?,6?-triisopropyl-1,1?-biphenyl)[2-(2-aminoethyl)phenyl)]palladium(II) (8.43 mg, 0.011 mmol) and K3PO4.H2O (63.1 mg, 0.274 mmol) in a vial under an inert atmosphere was added THF (1.5 mL). The vial was sealed and heated at 100¡ã C. for 2 h., cooled to rt and concentrated. The residue was taken in DMSO, filtered and the filtrate was subjected to reverse phase HPLC purification (Sunfire C18 30¡Á150 mm column; 10 to 95percent MeCN in water. 0.1percent TFA modifier for MeCN and water). Desired fractions were partitioned between saturated aqueous sodium bicarbonate and dichloromethane. Layers were separated. Aqueous layer was extrated with dichloromethane (3¡Á). Combined organic solutions were dried over Na2SO4 and concentrated to give desired product as a white solid (120 mg, 93percent). MS [M+H]+ 563.1. 1H NMR (400 MHz, CDCl3) delta 8.05-8.02 (m, 2H), 7.68-7.63 (m, 2H), 7.21-7.14 (m, 2H), 7.20-6.97 (m, 2H), 5.66 (s, 1H), 3.94-3.91 (m, 1H), 3.30-3.22 (m, 1H), 3.14-3.12 (m, 4H), 2.51-2.44 (m, 1H), 2.1-1.3 (m, 10H), 0.78-0.58 (m, 2H).
