A solution of 1-(benzyloxyimino-methyl)-4,4-dimethyl-cyclohexanecarboxylic acid (1.47 g, 5.11 mmol) in methanol (100 mL) at 0° C. under a nitrogen atmosphere was added a trace amount of methyl orange. A solution of saturated methanolic HCl was added until a persistent red color was observed. Sodium cyanoborohydride (0.42 g, 6.68 mmol) was added portionwise alternately with methanolic HCl to maintain the red color. The reaction mixture was maintained at 0° C. for an additional 2 h and the volatiles were removed in vacuo. The product was used without further purification. MH+292.
