Reaction Steps

A solution of 2.82 g (9.8 mmol) of N-dimethylaminomethylene-2-methoxy-4-nitro-benzenesulfonamide in 70 ml of DCM is mixed slowly at room temperature with 13 ml of a 1 molar solution of boron tribromide in DCM. After 5 hours, 3 ml of the 1 molar solution of boron tribromide in DCM is added again, and it is stirred for another 16 hours. The batch is mixed with MeOH and diisopropyl ether. The precipitate that is formed is suctioned off, washed with EtOH and diisopropyl ether and dried. 1.94 g (7.1 mmol, corresponding to 72% of theory) of the product is obtained.
