Procedure: Synthesised from 5-bromo-2-chloro-4-(trifluoromethyl)pyrimidine (1.14 g, 4.35 mmol) and 1,4-diazepan-5-one (490 mg, 4.30 mmol) in accordance with General Method B, giving the title compound (1.20 g, 81%) as a white solid. δH (300 MHz, DMSO-d6) 8.79 (s, 1H), 7.71 (t, J 4.8 Hz, 1H), 3.90 (m, 4H), 3.21 (m, 2H), 2.54 (m, 2H). LC-MS (pH 3) MH+ m/z 339.0, RT 1.93 minutes. LC-MS (pH 10) MH+ m/z 339.0, RT 1.91 minutes.

Conditions: temp:100.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: (2-Chloropyrimidin-5-yl)boronic acid (200 mg, 1.26 mmol) and 1,4-diazepan-5-one (288.34 mg, 2.53 mmol) were suspended in 1,4-dioxane (3 mL) and the mixture was heated at 100° C. under microwave irradiation for 45 minutes. The resulting slurry was concentrated under vacuum and triturated with MeOH to afford the title compound (145 mg, 30%) as a cream precipitate, which was used without further purification. Method C HPLC-MS: MH+ m/z 237, RT 0.40 minutes. The resulting slurry was concentrated under vacuum triturated with MeOH
