[0476] To intermediate compound I-5 (7.5g, 18.19mmol) in THF / H 2 Add Pd(AcO) to a solution in O (10:1, 180 mL) 2 (0.12g, 0.54mmol), XantPhos (0.52g, 1.09mmol), Cs 2 CO 3 (23.88 g, 72.76 mmol) and intermediate compound 1-20 (4.51 g, 21.82 mmol). The reaction mixture was closed in a sealed tube and stirred at room temperature for 10 min and then at 114 °C for 45 min. Then, the crude mixture was washed with EtOAc and H 2 Diluted with O, the organic layer was separated and dried (MgSO 4 ), filtered and the solvent was concentrated in vacuo. The crude mixture was purified by chromatography (silica, MeOH in DCM, 0 / 100 to 2 / 98), the desired fractions were collected and the solvent was concentrated in vacuo to give ...

[0483] B-2 was synthesized as previously described for the synthesis of final compound B-1a. Starting from I-11a (0.2 g, 0.45 mmol) and intermediate I-20, the final compound B-2 (0.03 g, 14%) was obtained. 1 HNMR (300MHz, DMSO-d 6 )δppm 0.93(t, J=7.4Hz, 3H), 1.44(sxt, J=7.3Hz, 2H), 1.73(quin, J=6.9Hz, 2H), 2.93(br.s., 1H), 2.97( s,3H),3.19(br.s.,1H),3.77(br.s.,2H),3.92(br.s.,2H),3.98-4.14(m,2H),4.31(br.s. ,2H),5.76(s,2H),7.25(br.s,1H),7.33-7.50(m,2H),7.73(d,J=8.8Hz,1H),7.96(br.s.,1H) , 8.16 (d, J=8.1 Hz, 1H), 11.31 (br.s., 1H).

[0486]

[0487] To a stirred solution of Intermediate 1-8 (2.3 g, 7.12 mmol) dissolved in DCE (50 mL) was added morpholine (1.37 mL, 15.67 mmol) and the mixture was heated at 80 °C for 15 min under microwave irradiation (with The reaction was divided into three batches). Sodium triacetoxyborohydride (1.81 g, 8.55 mmol) was then added in portions and the mixture was heated again under the same conditions as described before for 20 min. The mixture was then treated with H 2 O quenched and extracted with DCM. The organic layer was separated and dried (Na 2 SO 4 ), filtered and evaporated the solvent in vacuo. The crude compound was purified by chromatography (silica, MeOH in EtOAC, 2 / 98 to 10 / 90), the desired fractions were collected and the solvent was evaporated to give the final compound as a light yellow solid B-3 (1.6 g, 57%), this compound was further washed with ...

Abstract

The present invention relates to combinations of phosphodiesterase 2 (PDE2) inhibitors with inhibitors of phosphodiesterase 10 (PDE 10). In particular, the invention relates to combinations of 1-aryl-4- methyl-[1,2,4]triazolo[4,3-a]-quinoxaline derivatives which have been found to inhibit phosphodiesterase 2 (PDE2), with inhibitors of phosphodiesterase 10 (PDE10). Particular PDE10 inhibitors are selected from the group of MP-10, PQ-10, TP-10, papaverine, and the compounds disclosed in WO 2011 / 051342 and in WO 2011 / 110545. The invention is also directed to pharmaceutical compositions comprising such combinations, to processes for preparing such compositions, to the use of PDE2 inhibitors, in particular of 1- aryl-4-methyl- [1,2,4]triazolo[4,3-a]-quinoxaline derivatives for the potentiation of said PDE10 inhibitors, and to the use of said PDE10 inhibitors for the potentiation of the effect of said PDE2 inhibitors, in particular, 1-aryl-4-methyl-[1,2,4]triazolo[4,3-a]-quinoxaline derivatives, and to the use of such combinations and compositions for the prevention and treatment of disorders in which PDE2 and PDE10 are involved, such as neurological and psychiatric disorders, and endocrinological or metabolic diseases.
