Diethyl Ether → 2-Amino-4-(3-cyanophenyl)-5-carboethoxythiazole

Participants

Reaction Conditions

Reaction Steps

To a solution of ethyl 2-bromo-3-(3-cyanophenyl)-3-oxopropionate (4.0 g, 13.5 mmol) in 100 mL of tetrahydrofuran was added thiourea (1.03 g, 13.5 mmol). The resulting mixture was stirred at 65° C. for 16 h. The reaction was allowed to cool and the solvent was evaporated in vacuo. The residue was triturated with ether, taken up in ethyl acetate, washed with saturated aq Na2CO3 and brine, dried (MgSO4) and concentrated in vacuo to yield a solid. Trituration with ethyl ether left the title compound as an off-white solid (3.79 g, 98%).
