It is used as a building block used in a multikilogram synthesis of a chiral naphthalenoid histamine receptor antagonist.

(R)-2-Methyl-pyrrolidine, an optically active amine that can be used as a key building block to synthesize:
4,5-fused pyridazinone derivatives are applicable as potent histamine H3 receptor antagonists.
Naphthalenoid histamine H3 receptor antagonist.
Pyrrolo[2,3-d]pyrimidine derivatives as potent inhibitors of leucine-rich repeat kinase 2.

ChEBI: (R)-2-methylpyrrolidine is a 2-methylpyrrolidine that has (R)-configuration. It is a conjugate base of a (R)-2-methylpyrrolidinium.

The general procedure for the synthesis of 2-methylpyrrolidine from 2-methylpyrroline was as follows: the whole-cell biotransformation reaction was carried out in sodium phosphate buffer (100 mM, pH 7.0) at 30 °C and 1000 rpm. Freshly harvested resting cells of E. coli BL21(DE3) expressing IRED with a final OD600nm adjusted to 90 were used.The reaction mixture contained 2.5 or 5 mM of imine substrate and 50 mM of glucose.
