50.3. 4-[(R)-2-tert-Butoxycarbonylamino-3-(diethoxy-phosphoryl)-propionyl]-piperazine-l- carboxylic acid butyl ester: To a solution of intermediate 50.2 (7.37 g) in DCM (95 mL), THF (24 mL) and DIPEA (16.3 mL) were added HOBT (3.83 g) and EDC-HCl (4.78 g), and the reaction mixture was stirred at RT for 10 min. Subsequently, piperazine- 1 -carboxylic acid butyl ester (5.31 g) was added and the mixture stirred at RT for 2.5 h. The reaction mixture was diluted with DCM, the org. phase washed with sat. aq. NaHCO3 and the aq. phase re-extracted with DCM. The combined org. phases were washed with brine, dried over Na2SO^ and concentrated to dryness. Purification by CC (EtOAc/MeOH 1:0 to 9: 1) gave 7.66 g of the desired product. LC-MS: tR = 0.94 min; [M+H]+: 494.00
50606-32-1 Butyl piperazine-1-carboxylate 21963126, apiperazines compound, is more and more widely used in various fields.
