The 136 g of product obtained in Step A are diluted with 1.5 liters of methanol and hydrogenated in the presence of 5 g of 10% Pd/C under an H2 pressure of 1.2 bars. After 12 hours of reaction at ambient temperature, the solution is filtered and then concentrated in vacuo. 87 g of the expected product are obtained in the form of a beige powder.
