Procedure

A solution of (R)-3-[3-(4-chloro-phenoxy)-azetidin-1-yl]-1-methyl-propylamine (0.145 mg, 0.569 mmol) and (5-ethyl-[1,3,4]thiadiazol-2-yl)-carbamic acid phenyl ester (0.142 mg, 0.569 mmol) in DMSO is stirred at room temperature for 4 hours then partitioned between ethylacetate and water. The organic phase is washed with brine and dried over magnesium sulphate and evaporated. The crude product is recrystallised from hot ethylacetate to afford 1-{(R)-3-[3-(4-Chloro-phenoxy)-azetidin-1-yl]-1-methyl-propyl}-3-(5-ethyl-[1,3,4]thiadiazol-2-yl)-urea. [M+H] 410.14.
