The study includes preparation and characterisation of a new Mannich -β-amino carbonyl namely: (2R)-4-methyl-2-((S)(phenylamino)(p-tolyl)methyl)cyclohexan-1-one. was achieved from the reaction of 4-methylcyclohexan-1-one and aniline with 4-methylbenzaldehyde in a 1:1:1 mole ratio, respectively. Calcium chloride was used as catalyst and ethanol as reaction medium. A range of physico-chemical tools were used to charcteris the isolated compound. These include; FT-IR,  1 H-,  13 C-NMR, mass spectra, elemental analysis and melting point.
