実験手順

3.87 g of 2-tert-butyl-4-cyclobutyl-6-piperazin-1-yl-pyrimidine (14.1 mmol) were stirred in 30 ml of dimethylformamide at room temperature. 3.18 g of triethylamine (63.1 mmol), 0.235 g of sodium iodide (1.57 mmol), 2.96 g of (R)-(−)-1-acetoxy-3-bromo-2-methyl-propane (15.2 mmol) were added and the reaction mixture was stirred for 5 h at 95° C. The dimethylformamide was evaporated under reduced pressure. The residue was partitioned between 100 ml of dichloromethane and 100 ml of water. The organic layer was separated, dried over magnesium sulfate and evaporated under reduced pressure to give a brownish oil (5.64 g).
