Reaction Steps
A solution of (RS)-1-{3-[5-(4-methoxy-phenyl)-1H-[1,2,4]triazol-3-yl]-benzyl}-pyrrolidin-3-ol hydrochloride (1:1) (mixture of tautomers) (50 mg, 0.13 mmol) in CH2Cl2 (5 ml) was treated with triethylamine (26 mg, 0.26 mmol 2 eq.) and stirred for 30 min. at r.t. Acetyl chloride (11 mg, 0.13 mmol, 1 eq.) was added and stirring was continued for 1.5 hrs. After removal of the solvent the residue was chromatographed over 20 g SiO2 (Merck 230-400 mesh) with CH2Cl2-MeOH (2M NH3) 96:4. The resulting product was dissolved in ethanol at r.t. and an excess 1.45 N HCl/EtOH solution (0.1 ml, 0.14 mmol) was added. After 30 min. stirring the solvent was evaporated and the residue dried under high vacuum at 40° C. overnight affording the title compound (53 mg, 0.12 mmol, 96% yield) as a colorless solid. MS: m/e=393.2 (M+H+)
