Reaction Steps

Methyl 4-{5-[4-({(4S,5R)-5-[3,5-bis(trifluoromethyl)phenyl]-4-methyl-2-oxo-1,3-oxazolidin-3-yl}methyl)-2-(3-fluoroazetidin-1-yl)pyrimidin-5-yl]-6-methoxypyridin-3-yl}-3,5-dimethylbenzoate (EXAMPLE 32 Step A, 0.091 g, 0.122 mmol) was dissolved in ethanol (0.80 mL). Added hydrazine (0.115 mL, 3.65 mmol) and stirred at 85° C. in a screw cap vial (with a pressure relief cap) under a nitrogen blanket. The reaction was monitored by LCMS. Once complete the reaction was cooled to room temperature. The solvent was removed by rotary evaporation and the crude isolate was partitioned between ethyl acetate and water. Washed the organic twice more with water, then once with brine, dried over sodium sulfate, filtered and evaporated to give an off-white foam as the product. The compound was used without further purification. 1H NMR (CDCl3, 500 MHz): δ 8.15 (s, 1H), 8.00 (d, 1H), 7.88 (s, 1H), 7.74 (s, 2H), 7.51 (d, 2H), 7.43 (s, 1H), 7.27 (d, 1H), 5.70 (d, 1H), 5.51 (m, 0.5H), 5.40 (m, 0.5H), 4.69 (d, 1H), 4.45 (m, 3H), 4.29 (m, 2H), 3.99 (m, s, 4H), 2.14 (s, 3H), 2.13 (s, 3H), 1.65 (br, 2H), 0.74 (d, 3H).
