As a common heterocyclic compound, it belongs to thiazolidine compound, name is 1,1-Dioxo-isothiazolidine, and cas is 5908-62-3, its synthesis route is as follows.,5908-62-3
To a mixture of Cs2C03(41 mg, 0.12 mmol), 5-(5-(4-bromophenyl)- l,2,4-oxadiazol-3-yl)-l-(3-(2-methoxyethoxy)benzyl)pyridin-2(lH)-one(synthesized with analogous method to Example 65, using 4-bromobenzoic acid instead of 4-(trifluoromethoxy)benzoic acid; 30 mg, 0.062 mmol), Pd2(dba)3 (0.6 mg, 0.62 muiotaetaomicron), and XPhos (1.1 mg, 2.5 muiotaetaomicron) in toluene (311 muEpsilon) previously degassed with N2, was added isothiazolidine 1,1 -dioxide (6.4 mu, 0.075 mmol). The mixture was heated to 80 C for 12 h, cooled to RT, filtered through a pad Celite and concentrated under reduced pressure. The residue was purified by prep-HPLC (Mobile phase: A = 0.1% TFA/H20, B = 0.1% TFA/ MeCN; Gradient: B = 30% – 70% in 12 min; Column: CI 8) to give the title compound; H NMR (600 MHz, Chloroform-if) delta 8.25 (d, J = 2.4 Hz, IH), 8.13 (d, J = 8.8 Hz, 2H), 8.04 (dd, J = 9.5, 2.4 Hz, IH), 7.35 (d, / = 8.8 Hz, 2H), 7.28 (m, IH), 6.95 (d, / = 8.0 Hz, IH), 6.93 (m, IH), 6.88 (dd, / = 8.1, 2.4 Hz, IH), 6.77 (d, / = 9.5 Hz, IH), 5.22 (s, 2H), 4.14 – 4.04 (m, 2H), 3.87 (t, / = 6.5 Hz, 2H), 3.79 – 3.68 (m, 2H), 3.46 – 3.43 (m, 2H), 3.43 (s, 3H), 2.67 – 2.56 (m, 2H); MS (ES+) C26H26N406S requires: 522, found: 523 [M+H]+
With the complex challenges of chemical substances, we look forward to future research findings about 5908-62-3,belong thiazolidine compound
