Procedure

Into a 100 mL round-bottom flask, was placed a solution of N-(azetidin-3-yl)-2-(6-(trifluoromethyl)cinnolin-4-ylamino)acetamide (as prepared in the previous step, 450 mg, 1.38 mmol, 1.00 equiv) in dichloromethane (30 mL), 4-(1-hydroxypropyl)cyclohexanone (as described in Example 25, Step B) (216 mg, 1.38 mmol, 1.00 equiv), NaBH(OAc)3 (877 mg, 4.14 mmol, 3.00 equiv) and triethylamine (418 mg, 4.14 mmol, 3.00 equiv). The reaction mixture was stirred overnight at room temperature. The resulting mixture was concentrated under vacuum. The crude product (500 mg) was purified by Prep-HPLC with the following conditions (1#-Waters 2767-5): Column, SunFire Prep C18, 5 μm, 19×100 mm; mobile phase, Water and CH3CN (30% CH3CN up to 40% in 13 min, up to 100% in 0.1 min, hold 100% in 2 min, down to 30% in 0.1 min, hold 30% in 1.4 min); Detector, UV 220&254 nm. The title compound was obtained as a light yellow solid.
