Reaction Steps

To a solution of 2-(2,4-dimethyl-3-cyano-6-pyridylimino)-3-thia-1-azaspiro[4.4]nonane (Method C1e; 0.192 g, 0.669 mmol) and isobutyl bromide (0.5 mL) in anh. DMF (0.5 mL) was added NaH (95%; 0.62 g, 6.69 mmol) portionwise. The resulting mixture was heated at 50° C. for 3 h, then treated with MeOH (approximately 0.5 mL) and concentrated under reduced pressure. The residue was purified by chromatography (SiO2, gradient from 20% EtOAc/hex to 100% CH2Cl2) to give 2-(2,4-dimethyl-3-cyano-6-pyridylimino)-1-isobutyl-3-thia-1-azaspiro[4.4]nonane (0.04 g, 17%): CI-MS m/z 343 ((M+H)+).
