Step D: Preparation of 1,1-dimethylethyl 4-[4-(4,5-dihydro-5-phenyl-3-isoxazolyl)-2-thiazolyl]-1-piperazineacetate To a solution of 2-chloro-1-(4,5-dihydro-5-phenyl-3-isoxazolyl)ethanone (i.e. the product of Example 7, Step C) (0.450 g, 2.018 mmol) and 1,1-dimethylethyl 4-(amino-thioxomethyl)-1-piperazinecarboxylate (i.e. the product of Example 7, Step A) (0.5 g, 2.04 mmol) in ethanol (10 mL) was added triethylamine (0.204 g, 2.013 mmol), and the reaction mixture was stirred at room temperature for 12 h. The reaction mixture was concentrated under reduced pressure, and the residue was partitioned between ethyl acetate (30 mL) and water (30 mL). The organic layer was separated and washed with brine (25 mL), dried (Na2SO4), and concentrated under reduced pressure. The crude residue was purified by column chromatography using 20% ethyl acetate in petroleum ether as eluant to give 700 mg of the title compound as a white solid. 1H NMR (CDCl3): delta 1.48 (s, 9H), 3.30 (m, 1H), 3.54 (m, 8H), 3.74 (m, 1H), 5.71 (m, 1H), 6.91 (s, 1H), 7.40-7.29 (m, 5H).
196811-66-2, 196811-66-2 tert-Butyl 4-carbamothioylpiperazine-1-carboxylate 12093220, apiperazines compound, is more and more widely used in various.
