実験手順
To 0.015 g (0.10 mmol) 2,5-dimethyl-furan-3-carbonyl chloride in 1 mL DCM is added a mixture of 0.031 g (0.10 mmol) (S)-1-{4-[3-(4-ethoxy-phenoxy)-azetidin-1-yl]-phenyl}-ethylamine (X.1) and 0.010 g (0.10 mmol) TEA in 0.5 mL DCM. The mixture is stirred for 12 h at rt. The solvent is removed in vacuo and the residue is purified by HPLC to yield the desired product.
