Procedure

To a solution of 3-(4-(methoxymethyl)piperidine-4-carboxamido)phenyl dimethylcarbamate, from step D, and N,N-diisopropylethylamine (2 mL, 11.9 mmol) in isopropanol (5 mL) was added 4-chloro-5-methyl-7H-pyrrolo[2,3-d]pyrimidine (397 mg, 2.37 mmol). The reaction mixture was heated to 110° C. in a sealed high-pressure vial for 17 hours, during which time the mixture became homogenous. The reaction was concentrated under vacuum and purified by silica gel chromatography (3-5% methanol:CH2Cl2). The product was washed with cold methanol to provide the title compound as an off-white solid (462 mg, 42% yield).
