Versuchsvorschrift

Benzyl-2-[3-chloro-5-(3-[(dimethylamino)methyl]phenethylamino)-2-methyl-6-oxo-1(6H)-pyrazinyl]acetate (preparation 20) (100 mg, 0.21 mmol) was dissolved in ethanol (10 ml), treated with 10% Pd on carbon catalyst (20 mg), aq HCl (1 m, 0.1 ml) and stirred under a hydrogen atmosphere (20 psi, room temperature, 2 hr). The catalyst was removed by filtration, the solvent evaporated to dryness and the residue azeotroped with CH2Cl2 to give the desired product, slightly impure (white solid, 85 mg). 1H NMR (CD3OD) δ 2.30 (s, 3H), 2.80 (s, 6H), 3.00 (t, 2H), 3.60 (t, 2H), 4.20 (s, 2H), 4.70 (s, 2H), 7.30 (m, 2H), 7.40 (m, 2H). LRMS m/z=379.1 (M+1)+.
