Reaction Conditions:
in methanol at 20; for 0.333333 h;Cooling with ice;
Steps:
1 Example 1 N, the synthesis of N- diisopropyl -N- Mechiruetan-1,2-diamine
8.9mol / L under ice-cooling to a methanol solution 135mL of methylaminewas added dropwise methanol 72mL solution of diisopropyl aminoethyl chloridehydrochloride 24.0 g, was stirred for 20 minutes at room temperature. Theresidue and the reaction mixture was concentrated under reduced pressure togive was dissolved in chloroform, was added under ice-cooling 2 mol / L aqueoussodium hydroxide. The reaction mixture was extracted twice with chloroform, theorganic layer was concentrated under reduced pressure. The resulting residueamino silica gel column chromatography (hexane: chloroform = 5: 1 chloroformonly) to obtain the title compound 19.4 It was obtained g.
