実験手順
TFA (2 ml) was added dropwise to a solution of (R)-methyl 3-(tert-butoxycarbonyl(methyl)-amino)-2,3-dihydro-1H-indene-5-carboxylate (760 mg, 2.49 mmol, 1.0 eq.) in methylene chloride (10 ml) at 0° C. The reaction mixture was then stirred at RT for 2 h. After completion of the reaction, the reaction mixture was concentrated to afford the desired product which was used in the next step without further purification.
