Reaction Steps
To a solution of 2-chloro-3-nitrothiophene (1.13 g, 6.93 mmol) in NMP (10 mL) in a pressure vessel was added 2-tert-butylphenol (1.04 g, 6.93 mmol) and K2CO3 (1.0 g, 10.1 mmol). The reaction was flushed with nitrogen, sealed and then heated to 105° C. for 48 h. The reaction was cooled to rt, diluted with EtOAc (˜150 mL) and washed twice with saturated aqueous NaCl (2ט150 mL). The aqueous washes were then back extracted with EtOAc. The combined organics were dried over MgSO4, filtered and concentrated to yield the crude desired product.
