2-(2-oxobutyl)cyclohexane-1,3-dione

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

Procedure: 2-(2-oxobutyl)cyclohexane-1,3-dione (1000 gms, 4.995 moles) was suspended in toluene (6000 ml, 6 vol). The mixture was warmed to 85 deg c and stirred for 5 minutes. Benzylamine (562.6 gms, 5.25 moles, 1.05 eq) was added dropwise over 30-45 minutes. Following the addition the mixture turned to an amber colored solution. Heat was applied to the solution and water was azeotroped off until the reaction temperature reached 110° C. The reaction was allowed to stir at 110° C. for 2 hrs at which time ˜4000 mls of solvent was distilled off at atmospheric pressure. Solution was transferred to a flask and further evaporated to an amber viscous oil which was used directly in the following step. The mixture was warmed to 85 deg c the addition the mixture Heat was azeotroped off until the reaction temperature reached 110° C to stir at 110° C. for 2 hrs at which time ˜4000 mls of solvent was distilled off at atmospheric pressure Solution was transferred to a flask further evaporated to an amber viscous oil which
