Versuchsvorschrift

A solution of 26.6 mg (0.15 mmol) of N-(4-cyanophenyl)thiourea and 19 mg (0.15 mmol) of 1,3-dichloroacetone in 0.4 ml of DMF is stirred at +80° C. for 3 h. After cooling to RT, a solution of 50.9 mg (0.15 mmol) of the compound from Example 34A in 0.2 ml of DMF and 50 mg (0.6 mmol) of sodium bicarbonate are added. The mixture is then stirred at RT for 12 h. The reaction mixture is filtered and purified directly by preparative HPLC (column: Macherey Nagel VP50/21 Nucleosil 100-5 C18 Nautilus, 5 μm, 21 mm×50 mm; wavelength: 220 nm; flow rate: 25 ml/min; mobile phase A=water+0.1% formic acid, mobile phase B=acetonitrile; gradient: 0 min 10% B→2 min 10% B→6 min 90% B→7 min 90% B→7.1 min 10% B→8 min 10% B). The product-containing fractions are combined and concentrated using a rotary evaporator.
