Versuchsvorschrift

TFA (10 ml) was added dropwise to a solution of (R)-methyl 3-(tert-butoxycarbonylamino)-2,3-dihydro-1H-indene-5-carboxylate (see step-2 product of A-17) (2.0 g, 6.87 mmol, 1.0 eq.) in methylene chloride (30 ml) at 0° C. The reaction mixture was then stirred at RT for 1 h. After completion (monitored by TLC), the reaction mixture was evaporated to afford the desired product as a colorless gummy solid which was used in the next step without further purification.
