Procedure

{(R)-2-[7-(1,4-dioxa-spiro[4,5]dec-8-yl)amino-5-methyl-1H-indol-2-yl]-4,5-dihydro-thiazol-4-yl}-acetic acid ethyl ester (177 mg, 4 mmol) prepared in Step A was dissolved in methanol (10 mL). HCl (conc. 2 mL) was added thereto, and the mixture was reacted for 6 h at 60°. The solvent was removed under reduced pressure, and water was added to the residue. The reaction mixture was extracted with EtOAc, dried, concentrated, and purified by HPLC to give the title compound (76 mg, Yield 50%).
