Reaction Steps

A mixture of 2-chlorobenzoxazole (1.00 g, 6.51 mmol), benzyl 1-piperazinecarboxylate (1.43 g, 6.51 mmol), and K2CO3 (1.80 g, 13.0 mmol) in DMF (13 mL) was stirred at 100° C. overnight, cooled, diluted with water, and extracted with EtOAc. The extracts were combined, washed with water and brine, dried over Na2SO4 and concentrated in vacuo to provide the title compound (1.70 g, 77%), characterized by NMR and mass spectral analyses.
