Reaction Steps

To (1R,2S)-1-(1-(4-fluorophenyl)-1H-indazol-5-ylthio)-1-phenylpropan-2-amine (0.024 g, 0.06 mmol) in MeOH (2.5 mL), 1,1,3,3-tetramethylguanidine (0.056 mL, 0.45 mmol) and ethyl trifluoroacetate (0.114 mL, 0.95 mmol) was added and the mixture was stirred at rt O/N and than submitted to purification on HPLC. The relevant fractions were collected freeze dried to give 16 mg of product (53% yield) which was analysed by LC/MS and NMR.
