N-methyloctadecanamide

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

Procedure: To 500 cc of acetone was added 15.5 g of methylamine to form a mixture. 60.0 g of stearoyl chloride was drop-wise added to the mixture, while the mixture was stirred and cooled using ice water. The addition was conducted at a temperature of not higher than 20° C. Further, 20.2 g of triethylamine was dropwise added to the mixture at a temperature of not higher than 20° C. After the addition was complete, the mixture was allowed to react for 3 hours. The reaction mixture was then poured into water and the aqueous mixture was filtered to collect produced crystals, and the crystals were recrystallized from a mixed solvent of ethyl acetate and methanol to give a white crystalline product of N-methylstearic amide (Amide compound No. 1 mentioned above). to form a mixture cooled The addition higher than 20° C After the addition to react for 3 hours the aqueous mixture was filtered to collect produced crystals the crystals were recrystallized from a mixed solvent of ethyl acetate and methanol
