The present invention relates to compounds of formula (I), wherein R1 is selected from: (a) (C1-C6)alkyl, optionally substituted by 1-3 substituents, each independently selected from: (i) CF3, OH, (C1-C6)alkyl, (C3-C6)cycloalkyl, (C1-C6)alkoxy and halo. (ii) Phenyl, optionally fused with phenyl or cyclohexyl, said phenyl or fused phenyl optionally substituted with 1-3 groups selected from (C1-C6)alkyl, (C1-C6)alkyl ester, OH and halo; and (b) (C3-C6)cycloalkyl, optionally fused with (C5-C7)cycloalkyl, said cycloalkyl or fused cycloalkyl optionally substituted by OH, (C1-C6)alkyl, (C1-C6)alkoxy and halo. R2 is Phenyl, optionally fused to (C4-C6)cycloalkyl, phenyl or pyridyl, said phenyl or fused phenyl moiety optionally substituted with 1-3 groups each independently selected from (C1-C6)alkyl, (C1-C6)alkoxy, halo and OH; n is 1 to 2; and pharmaceutically acceptable salts, solvates or polymorphs thereof; With the proviso that when n is 2 and R1 is 2-(3,4-dimethoxylphenyl)-1-ethyl, 3,3-diphenyl-1-propyl or 2,4-difluorophenyl, then R2 cannot be 4-trifluoromethoxyphenyl, 2,4,6-trimethoxyphenyl, 4-acetoxyphenyl or 2,4-difluorophenyl; which are a class of selective serotonin re-uptake inhibitors (SSRIs).
摘要:
Conventional biological processes for treating wastewater include the so-called activated sludge process which is continuous and the sequencing batch reactor (SBR) activated sludge process. The first process requires the use of dedicated, relatively expensive external clarifiers, and the second process is inefficient in terms of treatment volume. A modified sequencing batch reactor process and system enable the efficient, continuous treatment of wastewater, combining the advantages of the SBR and activated sludge processes. Wastewater is treated in three contiguous treatment sections, each of which includes a plurality of contiguous cells. In a first series of operations, the flow direction is from the first to the third sections, and in a second series of operations the flow is reversed. In each series of operations, the first step is to aerobically treat the wastewater, and then allow the sludge to settle before discharging the treated wastewater from the system. The settling steps of the process include pre-settling while wastewater is flowing through a section, and quiescent settling while aerobic treatment and flowing or pre-settling are occurring in other sections of the system.
