Green synthesis method for forming substituted pyrroles

A green method of forming an N-substituted pyrrole using an organic catalyst, comprising:

• reacting an amine of formula (2) with a compound of formula (3) in the presence of the organic catalyst,
• wherein the organic catalyst consists of juice from a fruit of a plant in the genus Malus,
• wherein the reacting includes mixing in a biphasic medium to form a compound of formula (1)
• wherein R1 and R2 are each independently a hydrogen, an optionally substituted alkyl, an optionally substituted cycloalkyl, an optionally substituted arylalkyl, or an optionally substituted aryl;
• and
• wherein R3 is an optionally substituted aryl.
