実験手順

A solution of 1,4,5-triphenyl-2-(7-bromoheptyloxy)-imidazole (1.75 g) and diethyl methylphosphonite (2.45 g) in toluene (10 ml) was heated at reflux temperature for 48 hours. Methanol and water were added and the mixture evaporated to an oil. This was chromatographed on silica gel (ethyl acetate/ethanol). The resulting oil slowly crystallised and was triturated with ether/petroleum ether, filtered then recrystallised from ethanol/ether to give ethyl 7-(1,4,5-triphenyl-imidazol-2-yloxy)heptane-methylphosphinate (1.06 g, 57%) as a white solid, m.p. 101°-2° C. Found: C, 72.05; H, 7.26; N, 5.52%; C31H37N2O3P; Requires: C, 72.07; H, 7.22; N, 5.42%.
