With lithium aluminium tetrahydride; at 0 - 50℃; for 3.25h; | A sample of <strong>[769965-95-9]5-fluoro-siprocyclopropyloxindole</strong> (172 mg, 97 jimol) was cooled in an ice/water bath and treated with a 1.0 M solution of LAH (1.94 ml, 1.9 mmol). The reaction was stirred at room temperature for 15 minutes and then at 50 C for 3 hours and finally was cooled back down with an icelwater bath. The reaction was treated with 1 M NaOH (1.9 mL) followed by water (1.9 mL). The reaction was filtered over celite and dried over MgS04. After filtration, the solvent was removed and the crude material of 5-fluoro- siprocyclopropylindoline was used without purification. | |

Intermediate H5'-F I uorospiro[cyc I op ropane-1 3'-i ndol i n]-2'-one5-Fluoroindolin-2-one (500 mg, 3.31 mmol) was dissolved in dry THF (30 ml). To this was added N1 ,N1,N2,N2-tetramethylethane-1,2-diamine (1.091 ml, 7.28 mmol) and the mixture was cooled to -78C. BuLi (1.6M in Hexanes) (4.14 ml, 6.62 mmol) was added dropwise and the contents left stirring for 20 mins. 1 ,2-Dibromoethane (0.342 ml, 3.97 mmol) was added dropwise and the mixture was stirred at -78C for 30 mins and allowed to warm to RT overnight. The reaction was quenched by addition of NH CI (20 ml) and extracted into EtOAc. The solvent was removed in vacuo and purification by chromatography on silica eluting with acetone/iso-hexane afforded the title compound as a white solid; 1H NMR (400 MHz, CDCI3) delta 8.40 (1H, s), 6.90 (2H, m), 6.60 (1 H, d), 1.80 (2H, m), 1.55 (2H, m). |

After this time, trans- methanesulfonic acid 4-{2-chloro-5-trifluoromethyl-benzoylamino)-cyclohexyl methyl ester (Intermediate C) (105 mg, 0.253 mmol) was added and the solution heated to 70C for 2.5 h. After cooling to RT overnight, the mixture was diluted with EtOAc/H20 (40 ml) and transferred to a separating funnel. The organic layer was separated and washed with brine, dried (MgS04), and concentrated in vacuo to give a light brown oil. The crude oil was chromatographed on silica eluting with a gradient of 0%-30% EtOAc/iso-hexane follwed by an isocratic gradient of 30% EtOAc/iso-hexane to afford the title compound as a white solid; LC-MS Rt= 1.36 mins; [M+H]+ 495.3; Method = 2minl_C_30_v002. 1H NMR (400 MHz, CDCI3). delta 7.90 (1H, s), 7.55 (1 H, d), 7.50 (1H, d), 6.95 (1H, m), 6.80 (1 H, m), 6.60 (1H, m), 5.95 (1 H, d), 4.0 (1H, m), 3.65 (2H, d), 2.20 (2H, m), 1.85 (5H, m), 1.55 (2H, m), 1.25 (4H, m). |
