Participants

Conditions

Temperature: 115 °C

Procedure

A mixture of 2-(tert-butyl-dimethyl-silanyloxy)-cyclohex-2-enone (6.9 g, 30.48 mmol) in dry toluene (50 mL) was treated with Bredereck's reagent (9.44 ml, 45.72 mmol) was stirred at 115° C. for 24 hours. The mixture was concentrated under reduced pressure to give 2-(tert-butyl-dimethyl-silanyloxy)-6-dimethylaminomethylene-cyclohex-2-enone as a semi-solid brown residue which was used as such in the next step.

Workup

concentrationThe mixture was concentrated under reduced pressure
