Versuchsvorschrift

1-Oxaspiro[2.6]nonane (2.5 g), 5-methyl-1H-pyrrole-2-carbonitrile (2.1 g) and Cs2CO3 (6.45 g) in N,N-dimethylformamide (15 mL) was heated at 120° C. in a Biotage Initiator microwave reactor for 30 minutes. The reaction mixture was diluted with ethyl acetate, washed with water and concentrated. The residue was purified by reverse phase chromatography, and was eluted with 30%-70% acetonitrile in 0.1% TFA water solution to provide the title compound.
