Participants

Reaction Steps

To the (1-Diazo-2-oxo-propyl)-phosphonic acid dimethyl ester (794 mg, 4.20 mmol) in 70 mL of methanol, add 1-(3,5-bis-trifluoromethyl-benzyl)-5-phenyl-1H-[1,2,3]triazole-4-carbaldehyde (1.44 g, 3.60 mmol) as a solution in 5 mL of methanol. To this mix, add (995 mg, 7.20 mmol) of potassium carbonate and mix the solution for 18 h. Dilute with ether and saturated NaHCO3, and extract with ether 3 times, wash the organics again with saturated NaHCO3, and dry the combined organics with MgSO4. Filter and concentrate. Purify by chromatography (silica gel, hexanes/EtOAc gradient) to provide 764 mg of the title compound. Exact Mass 395.09 spectrum (aspci): m/z=396.1 (M+1), 394.0 (M−1); 1H NMR (250 MHz, CDCl3) δ 7.73 (s, 1H), 7.55–7.40 (m, 4H), 7.42–7.30 (m, 3H), 5.52 (s, 2H), 3.21 (s, H).
