20120116125 | METHOD OF PREPARING NERAMEXANE - Method of preparing 1-amino-1,3,3,5,5-pentamethylcyclohexane or pharmaceutically acceptable salt thereof, comprising at least two steps selected from the following steps (i) to (iv):
| 05-10-2012 |
20120123166 | METHOD OF PREPARING 1-HYDROXY-1,3,3,5,5-PENTAMETHYLCYCLOHEXANE - Method of preparing 1-hydroxy-1,3,3,5,5-pentamethylcyclohexane comprising step (ii): (ii) converting 3,3,5,5-tetramethylcyclohexanone to 1-hydroxy-1,3,3,5,5-pentamethylcyclohexane by using methylmagnesium chloride. 1-hydroxy-1,3,3,5,5-pentamethylcyclohexane may be used for preparing 1-amino-1,3,3,5,5-pentamethylcyclohexane (Neramexane) or a pharmaceutically acceptable salt thereof. | 05-17-2012 |
20120130130 | METHOD OF PREPARING NERAMEXANE - The method of producing a salt of 1-amino-1,3,3,5,5-pentamethylcyclohexane comprising steps (i) to (v):
| 05-24-2012 |
20120130131 | METHOD OF PREPARING 1-AMINO-1,3,3,5,5-PENTAMETHYLCYCLOHEXANE - The invention relates to a method of producing 1-amino-1,3,3,5,5-pentamethylcyclohexane (Neramexane) or a pharmaceutically acceptable salt thereof comprising the step of heating a mixture comprising 1-chloroacetamido-1,3,3,5,5-pentamethylcyclohexane, thiourea and water. | 05-24-2012 |
20130123541 | METHOD OF PREPARING 3,3,5,5-TETRAMETHYLCYCLOHEXANONE - Method of preparing 3,3,5,5-tetramethylcyclohexanone comprising step (i): (i) converting isophorone to 3,3,5,5-tetramethylcyclohexanone in the presence of methylmagnesium chloride. The thus prepared 3,3,5,5-tetramethylcyclohexanone may be employed in a method of preparing 1-amino-1,3,3,5,5-pentamethylcyclohexane (Neramexane) or a pharmaceutically acceptable salt thereof. | 05-16-2013 |
