Reaction Steps
A solution of 1,1,1-trichloro-2-hydroxy-4-methyl-4-pentene (65 g) in pyridine (100 ml) was heated with acetic anhydride (65 ml) at 100° C. for 3 hours. The reaction mixture was poured into water (600 ml) and the resulting solution extracted with ether (3×200 ml). The combined other phases were dried over MgSO4 and the ether was evaporated. Distillation and re-distillation yielded 71.4 g (91%) of 1,1,1-trichloro-2-acetoxy-4-methyl-4-pentene. B.p. 92°-96° C./11 mm Hg.
