Reaction Steps

100 mg (0.32 mol) of 2-amino-6-sulfanyl-4-(2,3-dihydro-1,4-benzodioxin-6-yl)-3,5-pyridinedicarbonitrile [prepared analogously to Dyachenko et al., Russian Journal of Chemistry 33 (7), 1014–1017 (1997); 34 (4), 557–563 (1998)], 110 mg (0.64 mmol) of benzyl bromide and 108 mg (1.29 mmol) of sodium bicarbonate are stirred in 2 ml of DMF at room temperature for 5.5 h. Water is then added and the mixture is extracted three times with ethyl acetate. The combined organic phases are dried with magnesium sulfate and concentrated under reduced pressure. The residue is taken up in diethyl ether, giving, after reconcentration, a crystalline product.
