PROCEDURE

实验过程

A degassed mixture of 6-benzyl-4-chloro-1,7-dimethyl-6H-pyrrolo[2,3-e][1,2,4]triazolo[4,3-a]pyridine (200. mg, 0.644 mmol, Example 228, Step 7), tert-butyl 4-aminopiperidine-1-carboxylate (520 mg, 2.6 mmol, Combi-Blocks), NaOtBu (180 mg, 1.9 mmol, Aldrich), (9,9-dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine) (93 mg, 0.16 mmol, Aldrich) and tris(dibenzylideneacetone)dipalladium(0) (71 mg, 0.077 mmol, Aldrich) in toluene (10. mL) was heated at 120° C. for 4 hours. Upon cooling, the reaction mixture was diluted with EtOAc and washed sequentially with water and brine. The organic layer was dried over sodium sulfate, filtered and concentrated. Flash chromatography, eluting with a gradient from 0-5% MeOH in DCM afforded product as a light yellow solid (0.15 g, 49%). A portion (11 mg) of this solid was purified via preparative HPLC-MS (Waters XBridge C18, eluting with a gradient of MeCN/H2O containing 0.15% NH4OH). Yield: (7.1 mg, 65%).
