Versuchsvorschrift
2-[3-(Pyrid-2-yl)isoxazol-5-yl]pyrrolidine (Method 12) (1.5 g, 7 mmol) was added to a solution of N,N′-di(tertbutyloxycarbonyl)-N″-(trifluoromethylsulphonyl)guanidine (2.59 g, 6.6 mmol) and triethylamine (0.975 ml) in DCM and the mixture stirred at ambient temperature for 8 hours. The mixture was then washed with water, dried (MgSO4) and the volatiles removed by evaporation. The residue was purified by chromatography on silica gel eluting with DCM/methanol (100:0 increasing in polarity to 98:2) to give the title compound (2.3 g, 70%).
