실험 절차

To a stirred ethanolic suspension of 3-pyrrolidin-1-ylmethyl-benzamidine hydrochloride salt (1:2) (414 mg, 1.5 mmol, 1.5 eq.) in 15 ml ethanol was added over 3 minutes 1.2N NaOEt in ethanol (3.4 ml, 4 eq.) and stirring was continued for 30 min. at r.t. 4-Methylsulfanyl-benzoic acid hydrazide (182 mg, 1 mmol) in ethanol at 20° C. was then added and the mixture heated to reflux for 50 hrs. Upon cooling the product mixture was filtered, solvent evaporated and residue chromatographed over 20 g SiO2 (Merck 230-400 mesh) with CH2Cl2-MeOH (2M NH3) 96:4, affording a foam after solvent evaporation. This material was dissolved in ethanol at r.t. and an excess 2N HCl/ether solution (1.0 ml, 2 mmol) was added. After 30 min. the solvent was evaporated and the residue was dried overnight under high vacuum at 30° C. affording the title compound (200 mg, 52% yield) as a yellow foam. MS: m/e=351.5 (M+H+).
