実験手順

A solution of 1-{(S)-3-[3-(4-chloro-phenoxy)-azetidin-1-yl]-1-hydroxymethyl-propyl}-3-(3,5-dimethoxy-phenyl)-urea (0.05 g, 0.111 mmol) and triethylamine (0.031 ml, 0.222 mmol) in DCM (3 ml) is treated with acetic anhydride and left to stir at room temperature for 3 hours. The reaction mixture is partitioned between DCM and water. The organic phase is washed with sodium bicarbonate solution, dried over magnesium sulphate and evaporated to afford acetic acid (S)-4-[3-(4-chloro-phenoxy)-azetidin-1-yl]-2-[3-(3,5-dimethoxy-phenyl)-ureido]-butyl ester. [M+H] 492.08
