Reaction Steps

A solution of 5-(3-(3-(3-chloro-phenyl)-propylamino)-propyl)-thiophene-2-carboxylic acid methyl ester (from Preparation 8, 0.075 g, 0.213 mmol), DCC (0.0483 g 0.234 mmol) and nicotinic acid (0.0289 g, 0.234 mmol) in 10 mL CH2Cl2 was stirred at room temperature overnight. The mixture was filtered and the filtrate was concentrated in vacuo. The residue was dissolved in 15 mL EtOAc and the insolubles were removed via filtration. The organic solution was washed with water followed by brine, dried over MgSO4, filtered, and concentrated in vacuo to afford the title compound of Step A as an oil (113 mg). MS 457 (M+).
