Procedure

Amine preparation: to a THF (5 mL) solution of 3-hydroxymethyl-4-methanesulfonyl-piperazine-1-carboxylic acid tert-butyl ester (0.30 g, described for the production of 174) was added sodium hydride (0.043 g). The reaction mixture was stirred for 20 min and then iodomethane (0.19 mL) was added. After stirring for 24 h the reaction mixture was then diluted with DCM, washed with brine, dried (MgSO4) and the solvent removed in vacuo. The residue was purified by flash chromatography to yield 4-methanesulfonyl-3-methoxymethyl-piperazine-1-carboxylic acid tert-butyl ester (0.254 g). Treatment of this compound with HCl in DCM/MeOH yielded the desired amine, isolated as the hydrochloride salt.
