With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.278788-66-2,(R)-tert-Butyl 3-(hydroxymethyl)piperazine-1-carboxylate,as a common compound, the synthetic route is as follows.
To asolution of 5-(bromoacetyl)-2-fluorobenzonitrile (13.1 g, 0.054 mol) in DMF (160 mL) was added tert-butyl (3R)-3-(hydroxymethyl)piperazine-1-carboxylate (13.1 g, 0.065 mol) and K2CO3 (11.77 g, 0.075mol), and the mixturewas stirred at RTfor 3 h. The mixture was washed with water, and extracted with EtOAc. The organic layer waswashed with brine, dried over Na2SO4 and concentrated in vacuum to give the title compound which was used forthe next step without further purification.
278788-66-2, As the paragraph descriping shows that 278788-66-2 is playing an increasingly important role.
