Reaction Steps
A 25 mL round-bottomed flask was charged with a solution of 3-(4-hydroxypiperidin-1-yl)azetidine-1-carboxylic acid tert-butyl ester (0.34 g, 1.33 mmol) in DCM/TFA (4 mL/4 mL). The reaction mixture was stirred for 7 h at room temperature. The reaction mixture was loaded onto an Isolute® SCX-2 cartridge. The cartridge was washed with MeOH and the desired product was eluted using 2 M NH3 in MeOH to give 1-Azetidin-3-ylpiperidin-4-ol as a colourless oil (0.194 g, 94%). 1H NMR (CDCl3, 400 MHz) δ 3.75-3.68 (m, 1H); 3.67-3.51 (m, 4H); 3.25-3.17 (m, 1H); 2.66-2.56 (m, 3H); 2.03-1.84 (m, 5H); 1.65-1.53 (m, 2H).
