Procedure

Morpholine (350 μL, 4.0.0 mmol) is added to a solution of 4-chloromethyl-thiazol-2-ylamine hydrochloride (368 mg, 2.00 mmol) in DMF (7 mL). The reaction is stirred at 90° C. for 16 h. The reaction is diluted with ethyl acetate and washed with water. The aqueous layer is concentrated in vacuo and extracted with ethyl acetate. The combined organic layers are dried over MgSO4 and evaporated to give brown crystals which are used without further purification. 1H-NMR (400 MHz, d6-DMSO) δ=2.41-2.42 (m, 4H, CH2CH2), 3.30 (s, 2H, CH2), 3.55-3.60 (m, 4H, CH2CH2), 6.33 (s, 1H, Har), 6.85 (bs, 2H, NH2).
