A process for the preparation of aminoalkyl phenyl carbamate compounds of Formula I,
wherein R
1
and R
2
independently are hydrogen or a C
1-6
alkyl; R
3
and R
4
are the same or different and each is a C
1-6
alkyl; or R
3
and R
4
together with the nitrogen to which they are attached form a cyclic three to eight membered ring, with or without a heteroatom like nitrogen or oxygen; R
5
and R
6
independently are hydrogen, linear, branched or cyclic C
1-6
alkyl; or R
5
and R
6
together with the nitrogen to which they are attached form a cyclic three to eight membered ring, with or without a heteroatom like nitrogen or oxygen; the carbon centre designated “*” can be racemic or enantiomerically enriched in the (R)— or (S)-configuration; and pharmaceutically acceptable acid addition salts thereof.
一种制备化合物的
氨基烷基
苯基氨基甲酸酯的方法,其中式中R1和R2独立地是氢或C1-6烷基;R3和R4相同或不同,每个是C1-6烷基;或者R3和R4与它们连接的氮一起形成一个含有氮或氧等杂原子的环状3至8成员环,R5和R6独立地是氢、直链、支链或环状的C1-6烷基;或者R5和R6与它们连接的氮一起形成一个含有氮或氧等杂原子的环状3至8成员环;指定为“*”的碳中心可以是外消旋的或在(R)或(S)构型上富集的;及其药用可接受的酸盐。
