Versuchsvorschrift

To [2-[2-[1-[[4-[5-[(ethylamino)carbonyl]-2-methylphenyl]-3,4-dihydro-3-oxopyrazinyl]amino]-1-methylethyl]phenoxy]ethyl]methyl-carbamic acid phenylmethyl ester (Example 220d, 1.10 g) was added ethanol (10 mL) and this was pumped through a Pd/C cartridge at 1 mL/min under max H2 at 50° C. on an H-Cube hydrogenator. The solvents were removed in vacuo and the residue then taken up in acetonitrile. Purification by preparative HPLC (ACE column, 0.2% TFA:acetonitrile eluent) followed by treatment with SCX resin (eluting with methanol (discarded) followed by 7N NH3 in methanol and collected the basic fractions) and trituration with diethyl ether afforded the title product (2 mg).
