Reaction Steps

In a 500 ml Hastelloy-made autoclave having been purged with nitrogen were put 100 g (0.2886 mol) of the methyl 2-chloro-3-oxooctadecanoate (VII) prepared in (1) above, 2 ml of a methylene chloride solution of 260 mg (0.144 mol) of a ruthenium-optically active phosphine complex Ru2Cl4 [(+)-Tol-BINAP]2NEt3, and 300 ml of methanol, and the mixture was allowed to react at 50° C. under a hydrogen pressure of 30 atm for 18 hours. Methanol was removed by evaporation to give 95.8 g (0.275 mol; yield: 95.3%) of the title compound (VIII) (melting point: 39-40° C.).
