Procedure
A mixture of 2,7-diazaspiro[4.5]decan-1-one (50.0 mg, 0.000324 mol), 2-chloro-5-(trifluoromethyl)pyridine (71 mg, 0.00039 mol) and N,N-diisopropylethylamine (0.17 mL, 0.00097 mol) in N-methylpyrrolidinone (2 mL, 0.02 mol) was irradiated with microwaves at 180° C. for 20 min. The product was purified by prep-HPLC. LC-MS: 300.2 (M+H)+.
