Reaction Steps

A mixture of methyl 1-aminocyclopentanecarboxylate hydrochloride (2.00 g, 11.1 mmol, described in Intermediate 25), 2-bromoacetophenone (2.44 g, 12.2 mmol), and NaHCO3 (2.34 g, 27.9 mmol) in DMF (20 mL) was stirred at ambient temperature for 5 h. H2O (25 mL) was added and the mixture was extracted with EtOAc (2×75 mL). The combined organic layers were dried over Na2SO4, filtered, and concentrated in vacuo. The crude product was purified by HPLC using a reversed phase C18 column and eluting with a gradient of H2O:CH3CN:CF3CO2H-90:10:0.1 to 5:95:0.1. The product-containing fractions were combined, adjusted to pH 10 by addition of saturated aqueous Na2CO3 and extracted with EtOAc (2×75 mL). The combined organic layers were dried over Na2SO4, filtered, and concentrated in vacuo to provide the title compound. MS: m/z=262 (M+1).
