実験手順
2-(4-Chlorophenyl)-4-methylthiazol-5-yl methylamine (477 mg, 2.00 mmol), 1-tert-butoxycarbonyl nipecotic acid (459 mg, 2.00 mmol) and 1-hydroxybenzotriazole monohydrate (368 mg, 2.40 mmol) were dissolved in N,N-dimethylformamide (10 mL). While this mixture was chilled in an ice bath, 3-(3-dimethylaminopropyl)-1-ethylcarbodiimide hydrochloride (460 mg, 2.40 mmol) and N-methylmorpholine (0.484 mL, 4.40 mmol) were added. The mixture was then stirred at room temperature for 6 hours. Subsequently, 5% aqueous citric acid was added and the mixture was extracted with ethyl acetate. The extract washed sequentially with a saturated aqueous sodium bicarbonate solution and brine, followed by drying over magnesium sulfate and evaporation of the solvent. Purification of the residue by silica gel column chromatography (hexane:ethyl acetate=5:1->1:1) gave 916 mg (100%) of the desired compound as a colorless powder.
