2-(4-cyanophenyl)acetyl chloride

Conditions: temp:0.00; pressure:0.00; stir:

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

Procedure: Tetrahydro-1-(5-t-butyl-1,3,4-thiadiazol-2-yl)-3-methyl- 6-hydroxy-2(1H)-pyrimidinone (0.05 mole), triethylamine (0.06 mole) and benzene (50 ml) are charged into a glass reaction vessel equipped with a mechanical stirrer, thermometer and reflux condenser. α-(4-Cyanophenyl)acetyl chloride (0.05 mole) is then added dropwise with stirring. After the addition is completed, the reaction mixture is heated at reflux with continued stirring for a period of about 30 minutes. After this time the reaction mixture is filtered and the filtrate is stripped of solvent under reduced pressure to yield the desired product tetrahydro-1-(5-t-butyl-1,3,4-thiadiazol- 2-yl)-3-methyl-6-[α-(4-cyanophenyl)acetyloxy]-2(1H)-pyrimidinone as the residue. equipped with a mechanical stirrer thermometer and reflux condenser After the addition the reaction mixture is heated at reflux with continued stirring for a period of about 30 minutes After this time the reaction mixture is filtered

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

Procedure: Tetrahydro-1-(5-cyclopropyl-1,3,4-thiadiazol-2-yl)-3-methyl-6-hydroxy-2(1H)-pyrimidinone (0.05 mole), triethylamine (0.06 mole) and benzene (50 ml) are charged into a glass reaction vessel equipped with a mechanical stirrer, thermometer and reflux condenser. α-(4-Cyanophenyl)acetyl chloride (0.05 mole) is then added dropwise with stirring.
