Versuchsvorschrift

To a mixture of 6-(6-methoxy-5-trifluoromethyl-pyridin-3-yl)-4-((S)-pyrrolidin-3-yloxy)-5,6,7,8-tetrahydro-pyrido[4,3-d]pyrimidine (prepared using step 1, example 91 from intermediate 13) (44 mg, 0.11 mmol), 1-methyl-1H-pyrazole-4-carboxylic acid (15 mg, 0.12 mmol), benztriazol-1-ol (19 mg, 0.12 mmol) in CH2Cl2 (1.0 mL) was added EDC (34 mg, 0.18 mmol) and the resulting mixture was stirred at rt for 18 h. Partitioned between CH2Cl2 (10 mL) and sat. NaHCO3(aq) (2.0 mL) and the organic layer separated by filtering through a phase separation tube. Concentrated in vacuo and purified by flash chromatography through Biotage® amino silica gel eluting with cyclohexane/EtOAc, 100/0 to 0/100 to give {(S)-3-[6-(6-methoxy-5-trifluoromethyl-pyridin-3-yl)-5,6,7,8-tetrahydro-pyrido[4,3-d]pyrimidin-4-yloxy]-pyrrolidin-1-yl}-(1-methyl-1H-pyrazol-4-yl)-methanone as a white lyophilized powder (44 mg, 75% yield). 1H NMR (400 MHz, CDCl3-d, 298K) δ ppm 2.26-2.45 (m, 2H) 3.04-3.10 (m, 2H) 3.49-3.57 (m, 2H) 3.89-4.00 (m, 7H) 4.01 (s, 3H) 4.10-4.18 (m, 2H) 5.78-5.83 (m, 1H) 7.60-7.62 (m, 1H) 7.76-7.89 (m, 2H) 8.04-8.07 (m, 1H) 8.61-8.66 (m, 1H) MS: [M+H]+=504.2, Rt(3)=1.59 min. Example 55 was prepared using procedures analogous to those used in example 54 using appropriate starting materials.
