N-(propan-2-ylideneamino)methanamine

Conditions: temp:1.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a 1000 ml volume four-necked flask, 1-methyl-2-(2-propylidene)hydrazine (17-a) (9.61 g), acetonitrile (280 ml), and triethylamine (17 ml) were added under a nitrogen atmosphere and cooled to about 1° C. To the mixture, 2-(2,6-diethyl-4-methylphenyl)-2-oxoacetyl chloride (6-a) (27.12 g) dissolved in acetonitrile (77 ml) was added dropwise over 30 minutes. was added dropwise over 30 minutes

Procedure: 3-(ethoxymethylene)pentane-2,4-dione (Preparation 2, 8.6 g) was dissolved in Ether (30 mL) and cooled to 0° C. The reaction solution was then slowly treated with 1-methyl-2-(propan-2-ylidene)hydrazine (Preparation 1, 4.8 g) dropwise over 5 minutes, and then warmed and stirred at room temperature overnight. The reaction solution was purified directly by flash column chromatography (Biotage Quad 25; Eluent: 20% EtOH in EtOAc) to afford the title compound as a light red solid. (9.1 g, 84.0%). warmed The reaction solution was purified directly by flash column chromatography (Biotage Quad 25; Eluent: 20% EtOH in EtOAc)
