実験手順
A solution of (S)-3-[3-(4-Chloro-phenoxy)-azetidin-1-yl]-1-methoxymethyl-propylamine (1.6 g, 5.6 mmol) and (5-Ethyl-2-methyl-2H-pyrazol-3-yl)-carbamic acid phenyl ester (1.65 g, 6.7 mmol, see preparation below) in DMSO (7 ml) is stirred at ambient temperature for 4 hours, then partitioned between water and ethylacetate. The organic phase is washed again with water, dried over MgSO4 and evaporated. The crude product is purified by flash silica chromatography (elution with a 5:95 methanol/dichloromethane) to afford 1-{(S)-3-[3-(4-Chloro-phenoxy)-azetidin-1-yl]-1-methoxymethyl-propyl}-3-(5-ethyl-2-methyl-2H-pyrazol-3-yl)-urea. [M+H] 436.37.
