A mixture of 2.55 g (10.6 mmol) 3-Bromo-1-o-tolyl-propane-1,2-dione, 1.9 g (8.1 mmol) (3-thioureido-propyl)-carbamic acid tert-butyl ester and 5.66 ml (40.6 mmol) NEt3 in 100 ml methanol was heated to 80° C. for 2 h. The reaction mixture was evaporated under reduced pressure and the residue was purifier by flash column chromatography on silica eluting with a gradient of heptane and ethyl acetate. Evaporation of the product fractions yielded 2.17 g (71%) of the title compound as dark red oil.
