実験手順
To a solution of 41 in 2 mL dichoromethane, trifloroacetic acid (1 mL) was added. The reaction mixture was stirred for 2 h. At this point, LC-MS showed the reaction to be complete. The reaction was concentrated to remove the solvent and most of the TFA. The residue was then dried further in a high vacuum oven over 24 h to give the title compound 42 as TFA salt (100% yield).
