Reaction Steps

Under a nitrogen atmosphere a solution of 1.40 g (5.60 mmol) 4-methyl-2-oxo-2,3-dihydro-benzoxazol-6-sulphonic acid chloride and 1.60 g (16.8 mmol) N,N-dimethylacetamide in 1,2-dichloroethane was slowly added dropwise to 1.30 g (19.9 mmol) zinc and 2.40 mL (19.5 mmol) dichlorodimethylsilane in 20 mL of 1,2-dichloroethane. The reaction mixture was stirred for 2 h at 75° C. After cooling the mixture was filtered and the filtrate was evaporated down. The residue remaining was combined with MeOH, the precipitate formed was filtered and the filtrate was evaporated down. The residue was further reacted as the crude product.
