To a solution of 4-[4-(3-piperidin-1-yl-propoxy)-benzyl]-piperazine-1-carboxylic acid tert-butyl ester (D1) (1.576 g, 3.76 mmol) in a (1:1) mixture of dichloromethane and methanol (20 ml) was added a 1M solution of hydrogen chloride in diethyl ether (20 ml) and the reaction stirred for 5 hours at room temperature. The solvent was then evaporated in vacuo and the resulting residue triturated with diethyl ether to afford the title compound (1.5 g, 93%); MS (ES+), m/e 318 [M+H]+.
