Reaction Steps

A mixture of tert-butyl methyl(piperidin-4-yl)carbamate (465 mg, 2.173 mmol, 1.0 eq.), 4-chloropyridine-2-carbonitrile (300 mg, 2.173 mmol, 1.0 eq.) and K2CO3 (600 mg, 4.34 mmol, 2.0 eq.) in THF (4 ml) was heated for 48 hours at 100° C. in a pressure vessel. The mixture was filtered and washed with THF (10 ml). The filtrate was concentrated and purified by column chromatography (silica gel, 1% MeOH in DCM). Yield: 44% (300 mg, 0.949 mmol)
