Reaction Steps
A mixture of (R)-3-amino-1-N-Boc-piperidine (1 g), benzofuran-4-carboxylic acid (809 mg), PyBOP (2.6 g), DIEA (1.96 mL) in dry DMF (10 mL) was stirred at RT under nitrogen for 20 h. The reaction mixture was diluted with EA, washed with water. The aqueous phase was extracted twice with EA, the combined organic extracts were washed with brine, dried (MgSO4), filtered and concentrated to yield a crude light brown oil. FC (EA/n-heptane: 1/1 to EA) gave 1.41 g (82%) of the title compound as an oil.
