A mixture containing 1-(2-nitro-1-imidazolyl)-3-(2-hydroxyethylamino)-2-propanol (RSU-1137) prepared as described by Silver et al. [Silver, A.R.J., McNeil, S.S., O'Neill, P., Jenkins, T.C. and Ahmed, I., Biochemical Pharmacology 1986 35 3923-3928] (2.30 g, 10.0 mmol) and dimethylbromo-sulphonium bromide (2.22 g, 10.0 mmol) prepared by the method of Furukawa et al. [Furukawa, N., Inoue, T., Aida, T. and Oae, S., J. Chem. Soc. Chem. Commun. 1973 212] in N,N-dimethylformamide (20 cm3) was stirred at 50° C. for 12 hours. The reaction mixture was concentrated in vacuo, digested in ethanol (10 cm3) and separated by preparative column chromatography using silica gel as the stationary phase and chloroform-methanol (9:1 v/v) as eluant. 1-(2-Nitro-1-imidazolyl)-3-(2-bromoethylamino)-2-propanol hydrobromide (0.68 g, 18.2%) was obtained as a yellow solid, m.p. 148.5°-150.5° C. after treatment of the eluate with ethereal hydrogen bromide.
