Chlorotrimethylsilane → HCID 56624785, compound

Participants

Reaction Steps

A mixture of 19 g (0.09 mol) of N-dichloroacetylpiperid-4-one, 7.5 g (0.099 mol) of propane-1,3-diol and 22.4 g (0.21 mol) of trimethylchlorosilane was boiled under reflux for 12 hours, while stirring. Thereafter, the reaction mixture was concentrated under reduced pressure and the residue was then subjected to brief incipient distillation under greatly reduced pressure. The resulting brown oil, which slowly crystallized completely, was recrystallized from 200 ml of toluene. 16 g (66.6% of theory) of N-dichloroacetyl-piperid-4-one propylene ketal of melting point 115° C. were obtained.
