Sasaki, Tadashi published the artcileHeteroaromaticity. VII. Application of the Horner reaction to benzimidazoles, Application In Synthesis of 4760-35-4, the publication is Yuki Gosei Kagaku Kyokaishi (1968), 26(1), 70-4, database is CAplus.
2-(α-Hydroxyethyl)benzimidazole (2 g.) in 50 ml. tetrahydrofuran is stirred for 2 days with 15 g. activated MnO2 to give 1.4 g. I (R = Ac) (Ia), m. 194°. I (0.01 mole) in 50 ml. tetrahydrofuran is stirred for 30 min. with 0.015 mole AcCl to give the following II (R, m.p., and % yield given): H, 112-13°, 90; Me, 115-16°, 100; CH2Cl, 108-9°, 83; Ac, 120-1°, 42. Also prepared are 2-chloromethylbenzimidazole ethiodide (m. 185-92°), N-methyl-2-chloromethylbenzimidazole (m. 92-4°), and N-methyl-2-hydroxymethylbenzimidazole (m. 146-7°); Horner reaction was then carried out. Thus, 2 g. diethyl benzylphosphonate in 20 cc. tetrahydrofuran is refluxed for 2 hrs. with 0.7 g. 50% NaH and 3 g. II (R = Ac) to give 11% III (R1 = Ac, R2 = Me), m. 124-6°. Similarly prepared are the following compounds: trans-III (R1 = Et, R2 = H) (m. 207-8°); trans-p-dimethylaminostilbene; trans-stilbene.
