4-(4-Fluorobenzoyl)piperidine → HCID 66626278, compound

Participants

Reaction Steps

A mixture of 4-(4-fluorobenzoyl)piperidine (0.300 g, 1.2 mmol), Trans-(2-Formyl-cyclopropylmethyl)-carbamic acid tert-butyl ester (0.294 g, 1.2 mmol), in 1, 2 dichloroethane (2 mL) was stirred for 4 h at room temperature and sodium triacetoxyborohydride (0.470 g, 2.2 mmol) was added and the resulting solution was stirred for 12 hours until the TLC indicated completion of the reaction. The mixture was filtrated and concentrated to dryness and purified with column chromatography on silica gel using CH2Cl2-CH2Cl2/MeOH (1-9:1). The product fractions were concentrated to give 0.288 g (0.74 mmol, 60% yield) of a white solid. MS (m/e): 391.3 (M+H+).
