4-(4-氨基-3,5-二甲基苄基)-2,6-二甲基苯胺

反应条件: temp:22.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 4,4′-Methylenebis(2,6-dimethylbenzeneamine) (1.25 g), methyl ethyl ketone (15 g), Pt(S)/C (0.10 g), and toluene (40.0 g) were charged into reactor. The reactor was purged 3 times with 110 psig (8.60×105 Pa) of H2 at 22° C. The reaction mixture was then stirred at 22° C. under 110 psig (8.60×105 Pa) of H2 for 4.5 hours. GC (conditions:100° C./5 minutes/10° C.-minute/270° C.) showed 35% conversion of 4,4′-methylenebis(2,6-dimethylbenzeneamine). The reaction mixture was then stirred for 4 hours at 60° C., after which GC showed 79.5% conversion of 4,4′-methylenebis(2,6-dimethylbenzeneamine). The reaction mixture was then stirred for 11 hours at 130° C., after which GC showed 100% conversion of4,4′-methylenebis(2,6-dimethylbenzeneamine), and a 96% yield of N,N′-di-sec-butyl-4,4′-methylenebis(2,6-dimethylbenzeneamine); the remaining 4% was determined to be N-sec-butyl-4,4′-methylenebis(2,6-dimethylbenzeneamine). The product was observed to be water-white in color, and the structure of the product was confirmed by GC-MS. The reactor was purged 3 times with 110 psig (8.60×105 Pa) of H2 at 22° C GC (conditions:100° C./5 minutes/10° C.-minute/270° C.) The reaction mixture was then stirred for 4 hours at 60° C. The reaction mixture was then stirred for 11 hours at 130° C.

实验步骤: To a suspension of 2a (0.50 g, 1.97 mmol) in absolute ethanol (2 ml) was added 2-pyridinecarboxaldehyde (0.56 ml, 5.91 mmol, 3 eq.) and one drop of formic acid. The mixture was stirred at 45° C. overnight. On cooling to room temperature the suspension was filtered, washed with cold ethanol and dried under reduced pressure to afford 17 as a yellow solid (0.28 g, 18%). On cooling to room temperature the suspension was filtered washed with cold ethanol dried under reduced pressure
