Reaction Steps

A solution of 5-bromo-thiazol-2-ylamine (70a, 10.0 g, 38.5 mmol), 4-methoxy-benzenethiol (4.70 ml, 38.5 mmol) and K2CO3 (21.0 g, 151 mmol) in DMF (100 mL) was heated at 80° C. for 1.0 hour and stirred further 16 hours at room temperature. The reaction mixture was quenched with water and extracted with ethyl acetate. The organic layer was washed with brine, dried over MgSO4(s), and concentrated under reduced pressure to give 5-(4-methoxy-phenylsulfanyl)-thiazol-2-ylamine (70b, 6.70 g).
