1-(Oxiran-2-ylmethyl)piperidine was synthesized using piperidine (Sigma-Aldrich, Inc., St. Louis, MO, USA) and epichlorohydrin (Tokyo Chemical Industry Co., Ltd., Tokyo, Japan) and the following procedure. An aqueous solution (3 mL) of 1000 mmol of epichlorohydrin was added to cooled piperidine (1000 mmol), and the mixture was stirred for 1 h at 273 K, followed by further agitation at 293 K for 30 min. Then, 30% NaOH aq was added to the mixture with stirring for 3 h. After the reaction was complete, the product was extracted with diethyl ether and rinsed with ultrapure water several times. The combined organics were dried over MgSO4. The solvent was evaporated, and the resulting light yellow crude product was purified with a Kugelrohr distillation apparatus. The colorless final product was confirmed by 1H NMR, 13C NMR, and mass spectrometry. 1H NMR (400 MHz, DMSO-d6) δH 1.36 (m, 2H, J = 5.7 Hz), 1.49 (m, 4H, J = 5.7 Hz), 2.15 (dd, 1H, J = 13.2 Hz, 6.4 Hz), 2.34–2.41 (m, 5H), 2.53 (dd, 1H, J = 13.6 Hz, 4.0 Hz), 2.67 (t, 1H, J = 5.2 Hz), 2.97 (m, 1H, J = 3.3 Hz). 13C-NMR (100 MHz, DMSO-d6) δC 23.9 (s), 25.5 (s), 44.2 (s), 49.8 (s), 54.4 (s), 61.1 (s). High-resolution mass spectrometry (HRMS) (electron ionization (EI)), m/z: calcd for C8H15NO 141.1154 [M]+; found 141.1156.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
