実験手順
To a solution of N-Boc-N-methyl-L-alanine (195 mg) in N,N-dimethylformamide (2.5 mL), N-methylmorpholine (246 μL) and isobutyl chloroformate (105 μL) were added under ice cooling, and the mixture was stirred at the same temperature for 2 minutes. To the reaction mixture, a solution of (1S,3R)-3-((2-chloro-4-methoxypyrimidin-5-yl)ethynyl)cyclohexaneamine (Q3) hydrochloride in N,N-dimethylformamide (2 mL) was added under ice cooling, and the mixture was stirred at the same temperature for 1 hour and 30 minutes. To the reaction mixture, saturated aqueous sodium hydrogencarbonate and ethyl acetate were added. The organic layer was separated, washed successively with water, saturated aqueous sodium hydrogencarbonate and saturated aqueous sodium chloride, and then dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography (eluent, 88 to 40% hexane in ethyl acetate) to obtain tert-butyl ((S)-1-(((1S,3R)-3-((2-chloro-4-methoxypyrimidin-5-yl)ethynyl)cyclohexyl)amino)-1-oxopropan-2-yl)(methyl)carbamate (Q4, 120 mg).
