YieldReaction ConditionsOperation in experiment
With lithium chloride;tetrakis(triphenylphosphine) palladium(0); In tetrahydrofuran; N,N-dimethyl-formamide; for 8h;Reflux; Inert atmosphere; To a mixture of (5-Bromo-thiazol-2-yl)-carbamic acid tert-butyl ester (1.0 g, 3.58 mmol) and tributyl(vinyl)stannane (3.14 ml, 10.74 mmol) in DMF-THF (1 : 1, 24 mL) were added Pd(PPh3)4 (206.9 mg, 0.179 mmol) and LiCl (455.6 mg, 10.74 mmol), then the mixture was refluxed for 8 h under Argon atmosphere. The resulting mixture was concentrated in vacuo and the residue was dissolved in sat. NaCl, then extracted with ethyl acetate (150 mL). The organic layer was washed with brine, dried over anhydrous sodium sulfate filtered and . concentrated under reduced pressure to get crude product which was purified by column chromatography (silica gel 100-200 mesh 20% ethylacetate in hexanes as eluent) to afford pure product. (0.817 g) NMR (CDC13, 400 MHz): delta 1.58 ( s, 9H), 5.13 ( d, J = 10.7 Hz, 1H), 5.42 (d, J = 17.2 Hz, 1H), 6.718 (dd, J = 17.2Hz, 10.8Hz, 1H), 7.19 (s, 1H).MS (EI) m/z = 227.1 (M + 1).
With lithium chloride;tetrakis(triphenylphosphine) palladium(0); In tetrahydrofuran; N,N-dimethyl-formamide; for 2h;Reflux; Step I: (5-Vinyl-thiazol-2-yl)-carbamic acid tert-butyl ester: (5-Bromo-thiazol-2-yl)-carbamic acid tert-butyl ester (0.200 gm, 0.71 mmol), tetrakis(triphenylphospine)palladium (0.042 gm, 0.036 mmol), lithium chloride (0.91 gm, 2.14 mmol), and tributyl (vinyl)stannate (0. 68 gm, 2.14 mmol) were taken in 8 ml of THF and 8 ml of DMF and reflux for 2 hrs. After completion of reaction THF was removed under reduced pressure on ratavapour and the residue was partioned between ethyl acetate (20 ml) and water (20 ml). The layers were separated. Aq. Layer was extracted with ethyl acetate (2x20 ml). The combined organic layer was washed with brine and dried over anhydrous sodium sulfate filtered and concentrated under reduced pressure to get the crude product which was purified by preparative TLC to get the pure product (5-Vinyl-thiazol-2-yl)-carbamic acid tert-butyl ester (0.137 gm,). 1H NMR- (CDCl3, 400 MHz): delta 1.57 (s, 9H), 5.12 (d, J = 10.8 Hz, 1H), 5.41 (d, J =17.2 Hz, 1H), 6.71 (dd, J = 17.6,11 Hz, 1H), 7.19 (s, 1H), 11.55 (bs, 1H). MS (EI) m/z: 227.1 (M + 1).
