Yield:-
Reaction Conditions:
with 1-methyl-pyrrolidin-2-one
Steps:
2 Example 2
Example 2 To a reaction vessel equipped with a mechanical stirrer, a thermometer, a condenser maintained at 70°C, a trap and nitrogen sparge tube are added dimethylsebacate (25 g, 109 mmoles), 2,2,6,6-tetramethyl-4-hydroxypiperidine (37.5 g, 239 mmoles) and N-methylpyrrolidinone (7 ml) and heated to 100°C. Then lithium amide (0.124 g, 5.4 mmoles) is added with agitation and the reaction mixture is heated to 150-155°C for 3 hours at atmospheric pressure. During this period, nitrogen is continuously introduced subsurface at a rate of 0.5 L/min. to remove the generated methanol. The completed reaction mass is then cooled down to 100°C and neutralized with glacial acetic acid. Analysis by gas chromatography indicated that 99% of bis(2,2,6,6-tetramethyl-4-piperidinyl)sebacate is obtained, based on the dimethylsebacate.
