Sodium Bicarbonate → N2-(1-Phenylethyl)-1,3-benzothiazole-2,7-diamine

Participants

Reaction Steps

To 0.165 g (0.55 mmol) of 7-nitro-N-(1-phenylethyl)-1,3-benzothiazol-2-amine in 10 mL of DMF was added 0.62 g (2.8 mmol) of stannous chloride dihydrate. The reaction was heated to 80° C. for 48 h and neutralized with saturated sodium bicarbonate. The mixture was filtered through celite and extracted with ethyl acetate. The extracts were dried in vacuo and purified by flash chromatography eluting with a 50-75% ethyl acetate/hexanes gradient mixture to give 0.016 g (11%) of the title compound as a light yellow solid.
