反応手順

0.1 g PtO2 was added to a solution of 3,3-dimethyl-1-[2-(6-(3-pyridyl)hex-5 ynoyl)perhydropyridazinyl] pentane-1,2-dione (0.3 g, 0.8 mmol) in 20 ml dry MeOH. The mixture was under hydrogenation at room pressure (1 atm) overnight. The product was obtained as clear oil after filtering the catalyst, concentration and purifying on a silica gel (0.125 g, 41%). Rf=0.18 (EtOAc). 1H NMR (CDCl3, 400 MHz): δ 0.89 (t, 3H, J=7.4); 1.24 (s, 6H); 1.38 (m, 2H); 1.66 (m, 10H)i 2.14 (m, 2H); 2.63 (m, 2H); 2.82 (m, 2H); 4.60 (m, 2H); 7.23 (m, 4H). Anal. Calcd. for C22H33N3O3: C, 68.19; H, 8.58; N, 10.84. Found: C, 68.40; H. 8.52; N, 10.62.
