실험 절차

To a solution of 4-chloro-5-methyl-7H-pyrrolo[2,3-d]pyrimidine (0.274 g, 1.64 mmol) in isopropanol (10 mL) were added 4-methylpiperidine 4-carboxylic acid hydrochloric acid from step A (0.294 g, 1.64 mmol) and triethylamine (0.654 mL, 4.92 mmol). The reaction was heated to 180° C. for 1 hour under microwave conditions, concentrated, taken up with ice water, and neutralized to pH 3 with 6 N aq. HCl to precipitate the product. The product was collected by filtration and dried under vacuum overnight to give the title compound (0.42 g, 75%) as a gray solid. MS (ES+) [M+H]+=275.2.
