piperidine-2-thione

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

Procedure: An acetone solution of 3.51 g. (0.03 mole) δ-thiovalerolactam and 6.75 g. (0.03 mole) α-bromophenylacetic acid was heated until the solid started to form. After the solution was cooled, the solid was collected which weighed 6.5 g. Recrystallization could be done with acetonitrile. The purified material had a melting point of 188°-192° (dec.). to form After the solution was cooled the solid was collected which Recrystallization
