- PREPARATION 1 4- (N ', N'-dimethylureido) -4-phenylpiperidine toluenesulfonate
- the starting product is 4-acetylamino-1-benzyl-4-phenylpiperidine prepared according to EP-A-0 474 561
- the oil obtained is dissolved in 200 ml of acetone, cooled to 5 ° C. in ice and then added at this temperature, drop by drop. , 19.5 g of sodium azide in 60 ml of water After 2 hours at RT, the acetone is evaporated and then extracted with toluene and washed with a 5% solution of NaHC ⁇ 3, with water, with saturated NaCl solution Dried over Na2S ⁇ 4, then the toluene is evaporated to 30% of the initial volume and brought to reflux for 1 hour. By dry evaporation, an orange oil is obtained which crystallizes to give 54 g of the expected compound.
- step B 5 g of the compound obtained in PREPARATION 2, step B are placed in 150 ml of ether and 1.05 g of pyrrolidine, diluted in 25 ml of ether, are added. Diluted with 100 ml of DCM and then stirred for 30 minutes at RT. It is evaporated to dryness and then taken up in ether. The product which is crystallized is filtered to obtain 5.23 g of the expected compound in the form of a white solid.
- step A the compounds according to the invention, of configuration (S) described in TABLE 4 are prepared.
- 61 g of the compound of the preceding step are mixed in solution in 200 ml of toluene and 120 ml of methylisobutyl ketone and then 39 ml of acid are added in 30 minutes hydrochloric The mixture is left to return to RT and then stirred for 1 hour and a half. The aqueous phase is extracted with 200 ml of AcOEt and then 49 ml of NaOH ION is added thereto.
- EXAMPLE 18 A solution of 5 g of compound of Example 16 in 10 ml of acetone is mixed with a solution of 0.9 g of succinic acid in 40 ml of acetone. After 12 hours with stirring at RT, it is filtered. the salt formed to obtain 4.87 g of the expected compound Purity
- EXAMPLE 19 A solution of 8.02 g of the compound of Example 16 is mixed in 25 ml of acetone and a solution of 1.57 g of benzoic acid in 15 ml of acetone After 3 hours with stirring at RT, the salt formed is filtered and then dried under vacuum at 50 ° C to obtain 7.48 g of the expected compound HPLC purity 99%
