[1-(2-aminoethyl)piperidin-4-yl]methanol

Conditions: temp:120.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A mixture of 1-(2-amino-ethyl)-4-piperidinemethanol (5.2 g), 2-chloro-3-methyl-pyrazine (5.0 g) and CaO (4.5 g) was stirred for 20 hours at 120° C. The reaction mixture was cooled and purified by column chromatography over silica gel (eluent: CH2Cl2/(CH3OH/NH3) 92/8). The pure fractions were collected and the solvent was evaporated, yielding 2.3 g (29%) 1-[2-[(3-methyl-2-pyrazinyl)amino]-ethyl]4-piperidinemethanol (intermediate 1). The reaction mixture was cooled purified by column chromatography over silica gel (eluent: CH2Cl2/(CH3OH/NH3) 92/8) The pure fractions were collected the solvent was evaporated

Procedure: A mixture of 1-(2-amino-ethyl)-4-piperidinemethanol (5.2 g), 2-chloro-3-methylpyrazine (5.0 g) and CaO (4.5 g) was stirred for hours at 120° C. The reaction mixture was cooled and purified by column chromatography over silica gel (eluent: CH2Cl2/(CH3OH/NH3)92/8). The pure fractions were collected and the solvent was evaporated, yielding 2.3 g (29%)1-[2-[(3-methyl-2-pyrazinyl)amino]-ethyl]-4-piperidinemethanol (intermediate 1).
