    • Except of the cases of ammonia and methylamine, where instead of the pure amines, aqueous solutions (25 and 35% respectively) were used.

    • note
    • Contrary to its tautomer, the hydroxypyrrolidinone 9a, in an attempt to record the UV spectrum (in ethanol solution), was observed to give a bathochromic shift of absorption bands to more intense absorptions, with a maximum at 275-276 nm characteristic of electronic spectrum of benzylidenepyrrolidinone 10a.

    • note
    • In the cases of methylamine and ammonia, aqueous solutions were used (35 and 25% respectively) and the reaction mixture after stirring for 2 days at room temperature was heated on a steam bath for 3h and was concentrated under vacuum to a solid residue.
