Nitrogen → Methyl 4-(cyclopropoxy)-3-[(4-methoxyphenyl)methylsulfanyl]benzoate

Participants

Reaction Steps

To a solution of methyl 3-bromo-4-(cyclopropoxy)benzoate (530.00 mg, 1.95 mmol, 1.00 eq) and (4-methoxyphenyl)methanethiol (451.12 mg, 2.93 mmol, 1.50 eq) in toluene (10.00 mL) were added Pd2(dba)3 (89.28 mg, 97.50 umol, 0.05 eq), Xantphos (112.83 mg, 195.00 umol, 0.10 eq) and DIPEA (504.04 mg, 3.90 mmol, 2.00 eq) under N2 protection. Then the mixture was stirred at 100° C. for 16 hr N2 protection. TLC detected the reaction was complete, the solvent was evaporated, the residue was washed with water, the aqueous layer was extracted with EA, the combined organic layer was dried over Na2SO4, concentrated, the residue was purified by silica gel chromatography (PE:EA=5:1) to afford product methyl 4-(cyclopropoxy)-3-[(4-methoxyphenyl)methylsulfanyl]benzoate (600.00 mg, 1.74 mmol, 89.34% yield) as white solid. LCMS: 345 [M+1].
