Sodium borohydride (2.5 g, 66 mM) was added in portions to an ice-water cooled suspension of 2,6-dimethyl-4-[2-(2-methylphenyl)acetamido]phenyl thiocyanate (B) (5.0 g, 16 mM) in ethanol (100 mL) and dimethoxyethane (100 mL). After 2 hours, water (200 mL) was added to the clear yellow solution. The mixture was acidified to pH4 with 2M HCl and extracted with ethyl acetate. The combined extracts were washed with water, then with saturated sodium chloride solution, and dried (MgSO4). The solvent was removed by evaporation to yield 2,6-dimethyl-4-[2-(2-methylphenyl)acetamido]benzenethiol as a cream coloured solid (4.89 g) which was used without characterisation.
