1-Mesylpiperazine hydrochloride (4.24 g) was added to a solution of methyl 6-chloronicotinate (1.7 g) and N,N-diisopropylethylamine (6.3 ml) in dimethylacetamide (20 ml) and the mixture was heated at 120° C. for 2 hours. The mixture was allowed to cool to ambient temperature and poured onto crushed ice/water (50 ml) to precipitate a tan solid. The solid was collected by filtration and dried at 80° C. for 18 hours in a vacuum oven, to give 1-mesyl-4-(5-methoxycarbonyl-2-pyridyl)piperazine (2.05 g),
