Procedure

A solution of cyclopropyl-methyl-(3-trimethylsilanylethynyl-phenyl)-amine (Intermediate 114, 0.05 g, 0.2 mmol) in methanol (5 mL) was treated with potassium carbonate (0.063 g, 0.46 mmol) and the resulting reaction mixture was heated at 80° C. for 3 h. The solvent was evaporated in vacuo, the residue was diluted with water and extracted with diethyl ether. The organic phase was dried over anhydrous magnesium sulfate, filtered and evaporated in vacuo to afford the title compound (0.035 g, 100%).
