V.2 2.

2. Preparation of ethyl 3,3-dimethyl-4-pentenoate A mixture of 2.02 g of 1,1-diethoxy-1-(3-methyl-2-buten-1-yloxy)ethane and 20 mg of phenol was heated for 12 hours at 150°-160°, during which time ethanol was evolved. Distillation of the residue gave 1.12 g (72% yield) of ethyl 3,3-dimethyl-4-pentenoate, b.p. 80°-83°/57 mm. Similarly, in the absence of phenol, 2.02 g of 1,1-diethoxy-1-(3-methyl-2-buten-1-yloxy)ethane was heated for 20 hours at 150°-160°. Distillation than gave 1.06 g (68% yield) of ethyl 3,3-dimethyl-4-pentenoate, b.p. 87°-89°/62 mm.
