Procedure

To a solution of 3-(4-(2-methoxyethoxy)piperidine-4-carboxamido)phenyl dimethylcarbamate from step D, and N,N-diisopropylethylamine (0.28 mL, 1.6 mmol) in isopropanol (1.0 mL) was added 4-chloro-5-methyl-7H-pyrrolo[2,3-d]pyrimidine (55 mg, 0.322 mmol). The reaction mixture was heated to 110° C. in a sealed high-pressure vial for 17 h, during which time the mixture became homogenous. The mixture was concentrated under vacuum and purified by prep HPLC (30×100 mm C18 column, 5-100% acetonitrile:water (10 mM NH4OAc), 15 min, 45 mL/min) to afford the title compound (17.4 mg) as a white solid.
