Procedure: 2 g (7.46 mmol) of 3-methyl-heptadecan-2-one (Compound No. 3 of Table 1) are introduced into 10 ml of diethylene glycol, and the mixture is treated with 1.11 g (22.4 mmol) of hydrazine hydrate and 1.2 g (29.85 mmol) of sodium hydroxide. The mixture is stirred for twenty hours at 200° C. When the mixture has cooled to room temperature, it is treated with 100 ml of water, acidified with hydrochloric acid, with cooling, and extracted three times using cyclohexane. The combined organic extracts are washed twice with a little water, dried over sodium sulphate and concentrated. Separation by column chromatography using cyclohexane as the eluent gave 1.0 g (53% of theory) of 3-methylheptadecane. When the mixture has cooled to room temperature with cooling extracted three times The combined organic extracts are washed twice with a little water dried over sodium sulphate concentrated Separation by column chromatography
