Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a microwave vial containing (E)-methyl 3-(4-((6-methoxybenzo[b]thiophen-3-yl)oxy)phenyl)acrylate (100 mg, 0.294 mmol) in DMA (2.5 mL) was added (R)-1-(2-bromophenyl)ethanol (118 mg, 0.588 mmol), chloro[2-(dicyclohexylphosphino)-3,6-dimethoxy-2′,4′,6′-tri-i-propyl-1,1′-biphenyl][2-(2-aminoethyl)phenyl]palladium(II) (BrettPhos Palladacycle 1st generation, 23.47 mg, 0.029 mmol), trimethylacetic acid (90 mg, 0.881 mmol) and potassium carbonate (122 mg, 0.881 mmol) The microwave vial was sealed, purged and back-filled with nitrogen. The reaction mixture subjected to microwave irradiation for 2 h at 150° C. Upon completion the reaction was diluted with EtOAc, and washed with water and brine. The combined organic layer was dried over anhydrous Na2SO4, filtered and concentrated in vacuo. The resulting crude material was purified by column chromatography (SiO2, 0-30% EtOAc/heptane) to afford (R,E)-methyl 3-(4-((2-(2-(1-hydroxyethyl)phenyl)-6-methoxybenzo[b]thiophen-3-yl)oxy)phenyl)acrylate (27.5 ms, 0.060 mmol, 20% yield). LC/MS (m/z, MH+): 459.0. was sealed purged back-filled with nitrogen irradiation for 2 h at 150° C Upon completion the reaction was diluted with EtOAc washed with water and brine The combined organic layer was dried over anhydrous Na2SO4 filtered concentrated in vacuo The resulting crude material was purified by column chromatography (SiO2, 0-30% EtOAc/heptane)

Procedure: To a solution of (R)-(+)-2-bromo-α-methylbenzyl alcohol (402 mg, 2.0 mmol) and diphenylphosphoryl azide (0.692 ml, 3.2 mmol) in THF (10 mL) was added 1,8-diazabicyclo[5.4.0]undec-7-ene (0.466 ml, 3.2 mmol). The mixture was heated at 50° C. for overnight, partitioned with H2O and AcOEt, and then adjusted to pH 7 by adding 1M HCl. The organic layer was dried with MgSO4, filtered and evaporated. The residue was purified by silica gel column chromatography [eluting with n-hexane/AcOEt=95/5] to give the title compound (381 mg, 84%). partitioned with H2O and AcOEt by adding 1M HCl The organic layer was dried with MgSO4 filtered evaporated The residue was purified by silica gel column chromatography [eluting with n-hexane/AcOEt=95/5]

Procedure: (R)-1-(2-Bromophenyl)ethanol (30.0 g) and (R)-glycidyl nosylate(50.3 g) were dissolved in N,N-dimethylformamide (300 ml), sodium hydride (7.76 g, 60% in oil) was added and the mixture was stirred at room temperature for 2 hr. 10% Aqueous citric acid (600 ml) was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The organic layer was washed successively with water and saturated brine, dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (hexane:ethyl acetate=6:1) to give the title compound (32.9 g). the mixture was extracted with ethyl acetate The organic layer was washed successively with water and saturated brine dried over anhydrous sodium sulfate concentrated under reduced pressure The obtained residue was purified by silica gel column chromatography (hexane:ethyl acetate=6:1)
