Reaction Steps

To a solution of 3-[2-ethyl-3-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenyl]-azetidine (D131) (295 mg, 0.735 mmol) in Acetonitrile (10 mL) was added potassium carbonate (305 mg, 2.206 mmol) and ethyl 4-bromobutanoate (0.158 mL, 1.103 mmol). The reaction solution was heated to 60° C. overnight. The solvent was removed in vacuo and the residue was diluted with ethyl acetate, washed with water, dried and concentrated to afford ethyl 4-{3-[2-ethyl-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]-1-azetidinyl}butanoate (D132) (295 mg) as an oil. MS (ES): C23H36BNO4 requires 401.3. found 402.3 (M+H+).
