Reaction Steps
To a solution of 5-bromo-2-fluorobenzaldehyde (4.06 g) in 2-propanol (20.0 mL) was added 2-methyl-2-propanethiol (2.26 mL) and K2CO3 (3.04 g) and heated overnight. The reaction mixture was cooled to room temperature, poured into 50.0 mL water and extracted with dichloromethane. The organic phase was washed with brine, dried over magnesium sulfate, filtered and concentrated. The residue was flash chromatographed (3% EtOAc/Haptanes) to obtain 1.97 g (36%) of 5-bromo-2-(tert-butylthio)benzaldehyde as a clear oil. 1H NMR (500 MHz, CDCl3) 8 ppm 1.30 (s, 9 H) 7.51 (d, J=8.05 Hz, 1 H) 7.70 (dd, J=8.29, 2.20 Hz, 1 H) 8.12 (d, J=2.20 Hz, 1 H) 10.70 (s, 1 H).
