実験手順

A mixture of methyl 1-[4-(chloroacetyl)phenyl]cyclopropanecarboxylate (0.30 g, 1.2 mmol) and thiourea (0.18 g, 2.4 mmol) in ethanol (5.0 ml) was refluxed overnight. The reaction mixture was diluted with ethyl acetate and washed with saturated NaHCO3 and brine successively; then dried; and then concentrated. The residue was tritrurated with ether followed by filtration to afford the product. LC-MS: 275.1 (M+H)+.
