Triethylamine → HCID 178457340, compound

Participants

Reaction Steps

To a stirred solution of 3-nitro-1,2,4-triazole (9.64 g, 84.50 mmol) and triethylamine (14.0 mL, 10.26 g, 101.4 mmol) in THF (200 mL) was added dropwise chloro-2-cyanoethoxy-N,N-diisopropylaminophosphine (20.0 g, 84.50 mmol) at room temperature. The mixture was stirred overnight at room temperature. The reaction mixture was filtered to remove the resulting salt, and the solvent was removed under reduced pressure to give the crude product as a pale brown oil (24.9 g, 95%). After standing at room temperature, the oil becomes a pale yellow wax-like solid. 1H NMR (CDCl3 δ 8.39 (s, 1H), 4.09 (m, 2H), 3.51 (m, 2H), 2.81 (m, 2H), 1.19 (d, J=6.0 Hz, 6H), 1.07 (d, J=9.0 Hz, 6H). 31P NMR (CDCl3) δ 133.9.
