Reaction Steps

To a solution of dimethylthiocarbamic acid S-(3-cyano-5,6,7,8-tetrahydronaphthalen-2-yl) ester (1.00 g, 3.84 mmol) in anhydrous N,N-dimethylformamide (10 mL) under argon was added dropwise 25% sodium methoxide in methanol (2.6 mL, 11.5 mmol, 3.0 eq) at 0° C. The resultant yellow reaction mixture was stirred at room temperature for 1 h. The reaction mixture was poured into cold 2N HCl (100 mL) and then extracted with ethyl acetate. The combined organic layers were dried over magnesium sulfate and evaporated at reduced pressure to give 700 mg (96%) of crude 3-mercapto-5,6,7,8-tetrahydronaphthalene-2-carbonitrile.
