Acetic Anhydride → HCID 14986818, compound

Participants

Reaction Steps

A mixture of 1.00 g of 4-(3′-chlorophenyl)-α,1-dimethyl-4-piperidinemethanol (Example 1) and 5 mL of acetic anhydride was heated under reflux for 90 minutes. Removal of the excess acetic anhydride and short-path distillation of the residue (170° C. bath temperature, 1 micron) gave 1.05 g of the title compound as an oil. 1H NMR (CDCl3): δ 7.1-7.4 (m, 4H); 4.9 (quartet, J=7 Hz,1H); 2.8 (m,2H); 2.2 (s,3H); 2.0 (s,3H); 1.9-2.4 (m,6H); and 0.9 (d,J=7 Hz,3H).
