Reaktionsschritte

A mixture of 3-bromo-2-fluorobenzaldehyde (5.0 g, 25 mmol), potassium carbonate (4.0 g, 30 mmol) and 2-methyl-2-propanethiol (5.5 mL, 49 mmol) in dry DMF (25 mL) was heated to 110° C. in a sealed tube for 16 h. The reaction mixture was cooled to RT, added to water (100 mL) and extracted with DCM (3×50 mL). The combined organic fractions were washed with water (50 mL), dried, and evaporated to afford 6.7 g (98%) of the crude title compound which was used without further purification. 1H NMR (300 MHz, CDCl3): δ 1.31 (s, 9H), 7.26-7.41 (m, 1H), 7.93-7.99 (m, 2H), 10.73 (s, 1H).
