실험 절차

643 mg (3.17 mmol) of 4-amino-2-(methylsulfonyl)-1,3-thiazole-5-carbonitrile (Example 6A) were dissolved in 16 ml of DMSO, and 500 mg (2.11 mmol) of tert-butyl 3-aminopiperidine-1-carboxylate and 3.49 ml (21.12 mmol) of N,N-diisopropylethylamine were added. The mixture was heated in a microwave at 120° C. for 45 min. The reaction mixture was taken up in a mixture of ethyl acetate and water. The organic phase was washed with saturated aqueous sodium chloride solution, dried over magnesium sulfate and concentrated on a rotary evaporator. The crude product was used without further purification.
