Procedure

In analogy to the procedure described for the synthesis of (6-Chloro-benzooxazol-2-yl)-pyrrolidin-3-ylmethyl-amine; hydrochloride (example 1, step 2) the title compound was prepared from (S)-3-aminomethyl-pyrrolidine-1-carboxylic acid tert-butyl ester and 2,6-dichloro-quinoxaline (commercially available) and subsequent cleavage of the tert-butyloxy carbonyl-protecting group through treatment with HCl in dioxane. MS (m/e): 263.1 (MH+).
