Participants

Reaction Steps

A mixture of ethyl 5-bromo-5-(4-chlorobenzoyl)valerate (17.4 g), thiourea (4.57 g) and ethanol (50 ml) was stirred with heating under reflux for 2 hours. The reaction mixture was poured into water (200 ml) and extracted with ethyl acetate (200 ml×2). The organic layer was dried over anhydrous magnesium sulfate and concentrated. The residue was recrystallized from ethanol to give ethyl 2-amino-4-(4-chlorophenyl)-5-thiazolebutanoate (14.6 g, 85%) as pale yellow prisms. Melting point 114-115° C.
