Triethylamine (0.047 ml) was added to a mixture of 4-[4-(cyclohexylacetyl)-1,3-thiazol-2-yl]piperidinium chloride (100 mg) in dichloromethane (1 ml). After the solid had dissolved completely, 4-chloro-2-isocyanato-1-methylbenzene (51 mg) and a drop of 1,8-diazabicyclo[5.4.0]undec-7-ene were added. The reaction mixture was then stirred for 5 minutes. Solvent and triethylamine were removed under reduced pressure. Purification of the residue by column chromatography gave N-(5-chloro-2-methylphenyl)-4-[4-(cyclohexylacetyl)-1,3-thiazol-2-yl]piperidine-1-carboxamide (128 mg).
