Procedure
NaH (0.016 g, 0.40 mmol) was stirred in anhydrous THF, 1.5 mL, under N2. 1-(2-Amino-3-chloro-pyridin-4-ylmethyl)-4-methyl-[1,4]diazepan-5-one (0.045 g, 0.17 mmol) was added followed after 10 min by the addition of 2-chloro-thiazole-5-carbonitrile (0.034 g, 0.23 mmol) and the reaction was heated to reflux. After 4 h the reaction was cooled to RT and quenched by the addition of water. The pH was adjusted to 7 with 1M HCl and the mixture was extracted 3× with EtOAc. The organic extracts were dried over Na2SO4, filtered and concentrated. The residue was purified by preparative reverse phase HPLC to afford a colorless oil. The residue was azeotroped 3× with MeOH and the resulting residue was dissolved in a minimum of MeOH. The solvent slowly evaporated to afford a white solid which was further dried in vacuo. TFA salt: 1H NMR (CD3OD) δ 8.46 (d, 1H, J=5.1 Hz), 8.12 (s, 1H), 7.34 (d, 1H, J=5.1 Hz), 4.43 (s, 2H), 3.75 (m, 2H), 3.36 (m, 4H), 3.02 (s, 3H), 2.88 (m, 2H). MS [M+H]+=377.2.
