N-CYCLOHEXYLBENZAMIDE

Conditions: temp:0.00; pressure:0.00; stir:

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

Procedure: 18 g of cyclohexylamine was dissolved in 150 ml of benzene. To the resulting solution was very slowly added 20 g of benzoyl chloride with stirring at temperatures below 40° C. White crystals separated from the mixture, generating white smoke. The mixture was stirred for one hour and was then made alkaline by addition of pyridine thereto. The product was filtered with suction. Crude crystals melting at 142° C. to 144° C. were recrystallized from a mixture of methanol and ethanol (1:1 in volume), from which white needles melting at 144° C. to 145° C. separated. The yield was 84%. White crystals separated from the mixture The mixture was stirred for one hour by addition of pyridine The product was filtered with suction Crude crystals melting at 142° C. to 144° C. were recrystallized from a mixture of methanol and ethanol (1:1 in volume), from which white needles melting at 144° C. to 145° C. separated

Procedure: Cyclohexylamine (8.5 mL, 0.1 mole) was added drop wise to a solution of benzoylchloride (1.17 mL, 10 mmol) in 35 mL of dry THF at 0° C. The reaction was then stirred at room temperature for 3 hours. After that time water was added and the mixture was poured onto crushed ice. A white solid precipitated. It was collected by filtration and rinsed thoroughly with water. The solid was then dried under vacuum (1.63 g, 80%). NMR 1H (ppm, CDCl3): 7.72 (d, J3=6.78 Hz, 2H), 7.48-7.36 (m, 3H), 6.02 (br. d., J3=6.58 Hz, 1H), 4.00-3.89 (m, 1H), 2.03-1.99 (m, 2H), 1.79-1.71 (m, 3H), 1.44-1.37 (m, 2H), 1.25-1.15 (m, 3H). the mixture was poured onto crushed ice A white solid precipitated It was collected by filtration rinsed thoroughly with water The solid was then dried under vacuum (1.63 g, 80%)
