Versuchsvorschrift

2-Methyl-4-methoxyphenyl thiourea (0.5 grams (g), 2.55 millimoles (mmol)) and bromomethyl isobutyrate were combined in 5 mL of acetone at ambient temperature, and the solution was allowed to stir for 18 hours (h). The solution was then cooled to 0° C. and the resulting solid was filtered and air-dried to give (E)-(N′-(4-methoxy-2-methylphenyl)carbamimidoylthio)methyl isobutyrate HBr (B1) (0.83 g, 82%): mp 127-130° C.; 1H NMR (CDCl3) δ 11.34 (s, 1H), 10.29 (s, 1H), 8.32 (s, 1H), 7.09 (d, J=8.7 Hz, 1H), 6.79 (d, J=2.8 Hz, 1H), 6.74 (dd, J=8.7, 2.8 Hz, 1H), 3.81 (s, 3H), 2.69 (heptet, J=7.0 Hz, 1H), 2.31 (s, 3H), 1.22 (d, J=7.0 Hz, 6H); ESIMS m/z 297 ([M+H]+).
