Epichlorohydrin → HCID 15670859, compound

Participants

Reaction Steps

To a mixture of epichlorohydrin (3.9 mL, 50 mmol) in EtOH (25 mL) and anhydrous NaHCO3 (4.2 g, 50 mmol), 1-piperonylpiperazine (11.0 g, 50 mmol) in EtOH (125 mL) was added dropwise over 45 min at 0° C., under nitrogen. After 16 h and removal of the EtOH in vacuo, the crude material was passed through silica gel (vacuum, 5% MeOH:CH2Cl2) to give pure product (3.85 g, 26.4%) as an amber oil. DCI/MS (M+1) 313. 400 MHz 1H NMR (CDCl3)δ: 7.25 (s, 1H), 6.7-6.8 (m, 2H), 5.9 (s, 2H), 4.6 (m, 1H),3.9 (m, 1H), 3.5 (m,2H), 3.4 (s, 2H), 2.4-2.7 (m, 10H).
