Versuchsvorschrift

A sealed tube equipped with a magnetic stirrer was charged with 222a (550 mg, 2.2 mmol), (3-(acetoxymethyl)-2-(7,7-dimethyl-1-oxo-3,4,7,8-tetrahydro-1H-cyclopenta[4,5]pyrrolo-[1,2-a]pyrazin-2(6H)-yl)pyridin-4-yl)boronic acid 199e (2.18 g, 5.5 mmol), Pd2(dba)3 (201 mg, 0.22 mmol), tricyclohexylphospine (84 mg, 0.30 mmol), Cs2CO3 (1.43 g, 4.4 mmol), dioxane (12 mL), and water (1 mL). After three cycles of vacuum/argon flush, the mixture was heated at 110° C. for 4 h. It was then filtered and the filtrate was evaporated in vacuo. The residue was purified by silica-gel column chromatography eluting with 30:1 ethyl acetate/methanol to afford 222b (310 mg, 25%) as a yellow solid. MS-ESI: [M+H]+ 568.6
