Reaction time: 1 h

Procedure:
2-Ethylamino-4-fluoro-5-nitro-phenol (910 mg, 4.5 mmol) was azeotroped with toluene to ensure dryness, then was dissolved in Tetrahydrofuran (100 mL) and was cooled at 0° C. 3-Bromo-1-propanol (0.65 mL, 7.2 mmol), Tributylphosphine (2.0 mL, 8.2 mmol), and 40% w/w DEAD in Toluene (3.8 g, 8.7 mmol) were added in succession, and the reaction was stirred under an atmosphere of Nitrogen overnight. The mixture was conc. in vacuo onto silica gel (10 g) and chromatographed (ISCO, 80 g silica gel, 0-35% EtOAc:Hex) to afford [2-(3-Bromo-propoxy)-5-fluoro-4-nitro-phenyl]-ethylamine as an orange solid. The bromide was dissolved in Tetrahydrofuran (100 mL) and Sodium hydride, 60% disp. in mineral oil (0.20 g) was added. After 2 h, no reaction was observed, so N,N-Dimethylformamide (5 mL) was added. After o.n. stirring, no reaction, so additional Sodium hydride, 60% disp. in mineral oil (0.35 g) was added and the mixture was heated at 65° C. After 4 h, the reaction was complete and was cooled to rt. The reaction was quenched with water, diluted with ether (300 mL) and washed with water (40 mL), satd. sodium bicarbonate (2×40 mL) and brine (80 mL), dried over sodium sulfate and conc. in vacuo onto 6 g silica gel. Chromatography (ISCO, 80 g silica gel, 0-30% EtOAc:Hex) afforded 9-Ethyl-2-fluoro-3-nitro-6,7,8,9-tetrahydro-5-oxa-9-aza-benzocycloheptene as an orange solid (517 mg, 47% two steps). 1H-NMR (CDCl3): 7.62 (d, 1H, J=7.9 Hz), 6.33 (d, 1H, J=14 Hz), 4.21 (t, 2H, J=6.5 Hz), 3.63 (t, 2H, J=5.8 Hz), 3.35 (q, 2H, J=7.0 Hz), 2.12 (m, 2H), 1.25 (t, 3H, J=7.0 Hz). 1687d) 9-Ethyl-2-fluoro-3-nitro-6,7,8,9-tetrahydro-5-oxa-9-aza-benzocycloheptene (515 mg, 2.14 mmol) and 10% Palladium on Carbon (50% Wet) (0.25 g) in Ethanol (30 mL) were shaken under an atmosphere of Hydrogen (40 psi) for 4 h. The mixture was filtered through Celite, washing with ethanol, and conc. in vacuo to afford 9-Ethyl-2-fluoro-6,7,8,9-tetrahydro-5-oxa-9-aza-benzocyclohepten-3-ylamine as a green film (0.375 g, 84%). 1H-NMR (CDCl3): 6.60 (d, 1H, J=12.8 Hz), 6.44 (d, 1H, J=9.2 Hz), 3.99 (m, 2H), 3.42 (s, 1H), 3.09 (m, 4H), 1.96 (m, 2H), 1.56 (m, 2H), 1.17 (t, 3H, J=7.0 Hz). 17e) 10-Camphorsulfonic acid (70 mg, 0.30 mmol) was added to 9-Ethyl-2-fluoro-6,7,8,9-tetrahydro-5-oxa-9-aza-benzocyclohepten-3-ylamine (58 mg, 0.28 mmol) and N-[(1R,2R)-2-(2,5-Dichloro-pyrimidin-4-ylamino)-cyclohexyl]-methanesulfonamide (94 mg, 0.28 mmol) in Isopropyl alcohol (1 mL). The mixture was irradiated in a CEM microwave (140° C., min) MP-Carbonate (2.69 mmol/g loading; 0.22 g, 0.5793156293 mmol) and DCM (2 mL) were added and the mixture stirred for 1 h, then filtered onto a 5 g SiO2 cartridge, which was air dried. The sample was chromatographed (ISCO, 2×12 g SiO2, 0-50% EtOAc:Hex) to afford N-{(1R,2R)-2-[5-Chloro-2-(9-ethyl-2-fluoro-6,7,8,9-tetrahydro-5-oxa-9-aza-benzocyclohepten-3-ylamino)-pyrimidin-4-ylamino]-cyclohexyl}-methanesulfonamide as a purple film (40 mg, 30%).
