Participants

Reaction Steps

To a solution of 5-chloro-2-hydroxy-benzaldehyde (9.3 g) in DMF (45 mL) was added DIPEA (20 mL) and tert-butyl-chloro-dimethyl-silane (19 g). The mixture was stirred at room temperature for 1.5 h. Then the mixture was poured into ice water (200 mL), extracted with ether (2×100 mL). The combined organic layers were washed with brine, dried over Na2SO4. The solvent was removed to give the title compound which was used directly for next step.
