Reaction Steps

To a stirred solution of 4-(4-chloro-6-methoxy-[1,3,5]triazin-2-ylamino)-piperidine-1-carboxylic acid tert-butyl ester (1.03 g, 3.0 mmol, 1.0 equiv) in acetonitrile (45 mL) was added N-ethyl diisopropylamine (1.56 mL, 1.18 g, 9.0 mmol, 3.0 equiv) at rt, followed by 2-amino-ethanol (0.36 mL, 0.37 g, 6.0 mmol, 2.0 equiv). The reaction mixture was heated to 50° C. for 3.5 h, then poured into crashed ice and extracted twice with ethyl acetate. The combined organic layers were washed with brine and water, then dried over MgSO4, filtered and concentrated by evaporation under reduced pressure. The crude product was purified by column chromatography on silica eluting with a gradient of dichloromethane/methanol to give 1.00 g (90%) of the title compound as colorless foam. MS (ISP): 369.1 [M+H]+.
