Procedure

To a solution of cis-racemic-3-hydroxy-4-[2-(2-isopropyl-2H-[1,2,4]triazol-3-yl)-4,5-dihydro-6-oxa-1,3a-diaza-benzo[e]azulen-8-yl]-piperidine-1-carboxylic acid tert-butyl ester (17 mg, 0.36 mmol) in DCM (1 mL) and methanol (0.6 mL) was added 4M HCl in dioxane (1.5 mL) slowly and the reaction mixture stirred at RT for 2.5 h before being concentrated in vacuo. The resultant residue was triturated in diethyl ether to give racemic cis-4-(2-(1-isopropyl-3-methyl-1H-1,2,4-triazol-5-yl)-5,6-dihydrobenzo[f]imidazo[1,2-d][1,4]oxazepin-9-yl)piperidin-3-ol which was resolved as the (3R,4S) enantiomer 328 as a white solid (10 mg, 67%). MS RT 2.47, [M+H]+=409. 1H NMR (DMSO-d6) δ: 8.92 (1H, br, d), 8.33 (1H, d, J=8.30 Hz), 7.97 (1H, s), 7.08 (1H, d, J=8.36 Hz), 6.96 (1H, d, J=1.66 Hz), 5.79 (1H, t, J=6.59 Hz), 4.50 (4H, d, J=7.99 Hz), 4.06 (1H, s), 3.27 (2H, m), 3.17 (2H, m), 2.97 (2H, d, J=14.58 Hz), 2.32-2.27 (1H, m), 2.29 (3H, s), 1.74 (1H, d, J=13.43 Hz), 1.46 (6H, d, J=6.59 Hz)
