A mixture of 27 mg (0.06 mmol) of (R)-3-tert-Butoxy-2-[(1-chloro-4-hydroxy-isoquinoline-3-carbonyl)-amino]-propionic acid tert-butyl ester and 2 ml of trifluoroacetic acid was stirred for 2 h at ambient temperature. Then the excess trifluoroacetic acid was evaporated in vacuo, the residue dissolved in 2 ml of absolute ethanol and the solution was concentrated in vacuo to give a tan solid. 27 mg of the title compound was obtained; MS-(+)-ion: M+1=310.9 amu.
