Participants

Reaction Steps

A mixture of 6 g (26.1 mmol) 7-bromo-benzooxazole-2-thiol, 7.28 g (52.2 mmol) K2CO3, 4.1 g (28.7 mmol) MeI in 80 ml DMF is stirred at room temperature for 1 h. The reaction mixture is then poured on water and extracted 2× with EtOAc. The combined organic layers are washed with water and saturated NaCl solution, dried over MgSO4, filtered and the filtrate is concentrated in vacuo to afford the title compound.
