2-Chioro-4-methyI-5-

Other poiyethyiene-type poiymers are made from monomers containing chioro, methyi, cyano, and phenyi substituents, as summarized in Tabie 22.7. In each case the double carbon-carbon bond in the substituted ethylene monomer becomes a single bond in the polymer. The different substituents lead to a wide variety of properties. [Pg.1028]

Preparation of J-Methy/ Lumilysergic Acid 8-Methyl Ester-10-Methyt Ether into a suspension of 10 grams of 1-methyi-iumiiysergic acid in 600 cc of absoiute methanoi a stream of anhydrous hydrogen chloride is bubbied for 1.5 hours with strong cooiing. The stream of hydrogen chloride is stopped and the mixture is aiiowed to stand for 30 minutes at 0°C, and is evaporated in vacuo to dryness. The residue is taken up with ice-cooied water made aikaiine with concentrated ammonia and extracted with chioroform. The combined chioro-form extracts are washed first with a 5% aqueous solution of sodium bicarbonate, then with water, and are thereafter dried over anhydrous sodium sulfate and finally evaporated in vacuo to dryness.

To a stirred solution of 20 g (0.1 mol) 2-carbethoxymethylene-3-methyl-4-thiazolidinone in 120 ml chloroform is added, dropwise, a solution of 5 ml (0.1 mol) bromine in 20 mi chioro-form. The solvent is removed by distillation and the residue crystaiiized from methanoi to yield 18 g (65%) of 2-carbethoxymethylene-3-methyi-5-bromo-4-thiazolidinone, MP 76°C. [Pg.612]

A mixture of 6.6 parts 1 -t4,4-di-(4-fiuoro-phenyi)butyi] -piperazine, 4.33 parts N-(2-chioro-acetyi)-2,6-dimethyi-aniiine, 3.2 parts sodium carbonate, a few crystais of potassium iodide in 200 parts 4-methyi-2-pentanone is stirred and refiuxed for 70 hours. After cooling there are added 70 parts water. The otganic layer is separated, dried over potassium carbonate, filtered and evaporated. The oily residue is dissolved in 80 parts diisopropyl-ether and the solution is filtered hot. After cooling the filtrate at 0°C, the formed solid is filtered off and recystaiiized from 80 parts ether, yielding 1 -[4,4-di-(4-fluoro-phenyl)butyl] -4-[(2,6-dimethyl-anilino-carbonyll-methyl] -piperazine MP 159°Cto 161°C.
