Procedure

2(R),6(R),10-trimethylundecanoic acid (270 mg., [α]D25 -8.64°) was dissolved in ether and treated with an excess of etheral solution of diazomethane at 23° C. for 2.0 hour. The crude product was subjected to evaporative distillation at 98°-101°/0.15 mm Hg to give 247 mg. of 2(R), 6(R),10-trimethylundecanoic acid methyl ester as a colorless oil, [α]D25 - 11.30° (c 1.1065, CHCl 3).
