Procedure

To a suspension of sodium hydride (17 mg of a 55% dispersion in mineral oil, 0.39 mmol) in DMF (5 ml) was added 2-methylimidazole (32 mg, 0.39 mmol). This mixture was stirred for 1.5 h at 20° C. Following this, 3-chloromethyl-5-(3,4-dichloro-phenyl)-pyridine hydrochloride (1:1) (100 mg, 0.32 mmol) and triethylamine (78 mg, 0.78 mmol) were added and the mixture heated to 100° C. for 4 h. After cooling, the DMF was evaporated and the residue was directly chromatographed [silica, elution with CH2Cl2/(2M NH3 in MeOH)=85:15] to afford the free base of the title compound as a yellow oil. This material was dissolved in MeOH, cooled to 4° C. with stirring and treated with HCl/EtOH (1.46 M 1.1 eq) for 15 min. Evaporation of the solvent and drying under high vacuum at 50° C. for 2 h afforded the title compound (71 mg, 62%) as a light yellow solid. MS: m/e=317.1 (M+)
