Participants

Reaction Steps

A mixture of cis-4-[(5S)-1-oxo-2,7-diazaspiro[4.5]dec-2-yl]cyclohexyl benzoate (19.0 mg, 0.0000533 mol), 2-chloronicotinonitrile (8.12 mg, 0.0000586 mol) and N,N-diisopropylethylamine (20.0 μL, 0.000115 mol) in N-methylpyrrolidinone (0.6 mL, 0.006 mol) was irradiated by microwave at 180° C. for 20 min. After cooling to rt, lithium hydroxide aqueous solution (1.0 M, 0.150 mL) was added, followed by methanol (0.2 mL). The mixture was heated at 100° C. for 5 h. The crude reaction mixture was then purified by prep-HPLC under basic conditions to afford the desired product. LC-MS: 355.2 (M+H)+.
