Procedure

A mixture of (2,6-dichloro-3-hydroxymethyl-pyridin-4-yl)-pyrrolidin-1-yl-methanone (400 mg, 1.45 mmol) and SOCl2 (1 mL) in CH2Cl2 (10 mL) is stirred at room temperature for 1 hour, and then concentrated. The residue is treated with K2CO3 (1.0 g, 7.2 mmol), CH3CN (10 mL) and (S)-methyl-(1,2,3,4-tetrahydro-naphthalen-1-yl)-amine (250 mg, 1.55 mmol). The resulting mixture is stirred at room temperature overnight. EtOAc (50 mL) and water (40 mL) are added to the residue. The organic layer is separated, washed once with brine, dried (Na2SO4) and concentrated. The residue is chromatographed on silica gel (4:1 hexane:EtOAc) to give the title compound.
