1-benzyl-3-methylpyrrolidin-2-one

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

Procedure: In a similar manner to that described in Example 1, 1-benzyl-3-methyl-2-pyrrolidone (14.1 g) in benzene (80 ml) was reacted with 4-(2-aminophenyl)morpholine (8.9 g) in benzene (30 ml) in the presence of phosphorus oxychloride (6.86 ml) for 24 hours at 70° C. to give 4-[2-(1-benzyl-3-methyl-2-pyrrolidinylideneamino)phenyl]morpholine (m.p. 96°-97° C.) which was recrystallised from hexane.
