Versuchsvorschrift

To a solution of the product of Intermediate 3 step a (305 mg, 1.80 mmol) in DCM (9 mL) was added 2-chloro-3-(trifluoromethyl)benzoic acid (404 mg, 1.80 mmol) followed by EDCI (517 mg, 2.70 mmol), HOBt (170 mg, 1.26 mmol) and TEA (0.50 mL, 3.60 mmol). The mixture was stirred overnight and then loaded directly on a column. Chromatography on SiO2 eluting with EtOAc/Hex afforded the desired product (267 mg, 39%) and 4-(1H-benzotriazol-1-yloxy)-7-{[2-chloro-3-(trifluoromethyl)phenyl]carbonyl}-5,6,7,8-tetrahydropyrido[3,4-d]pyrimidine (203 mg, 24%) as a side product. MS (ESI) mass calcd. C15H10Cl2F3N3O, 375.02. m/z found 376.0 [M+H]+. 1H NMR (500 MHz, CDCl3): 8.89-8.74 (m, 1H), 7.84-7.76 (m, 1H), 7.55-7.45 (m, 2H), 5.13-4.94 (m, 1H), 4.54-4.35 (m, 1H), 4.23-4.06 (m, 1H), 3.64-3.52 (m, 1H), 3.10-2.78 (m, 2H).
