Versuchsvorschrift

3-Cyclopentylmethoxy-5-phenoxy-pyridine-2-ylamine (0.97 mmol) is dissolved in THF (10 ml) and 1,1′-thiocarbonyldiimidazole (4 eq.) is added. The reaction solution is stirred 22 hours. 32% NH4OH (20 eq.) is added and stirred 2 hours at room temperature. Water (250 ml) is added and extracted with dichloromethane. The combined organic layers are washed with brine and dried over MgSO4. The solvent is removed in vacuo. (3-Cyclopentylmethoxy-5-phenoxy-pyridine-2-yl)-thiourea is obtained as yellow solid in a yield of 70%. HPLC (method C): 2.24 min; LC-MS (method A): 2.372 min, 344.15 (MH+).
