9-(1-(2-(tert-Butyldimethylsilyloxy)-2-methylpropyl)-2-methyl-1H-imidazol-4-yl)-2-(1-isopropyl-1H-1,2,4-triazol-5-yl)-5,6-dihydrobenzo[f]imidazo[1,2-d][1,4]oxazepine (110 mg, 0.196 mmol) was dissolved in 5 mL of THF, tetrabutylammonium fluoride (TBAF, 102 mg, 0.392 mmol) was added at 0° C. The temperature was allowed to warm up to room temperature slowly and stirred at room temperature for over night. Concentrated, the residue was portioned with EtOAc-water to give 30 mg of 265. Yield=36%. 1H NMR (CDCl3, 400 MHz): δ8.48 (d, J=8.0 Hz, 1H), 7.87 (s, 1H), 7.64 (s, 1H), 7.51-7.47 (m, 2H), 7.26 (s, 1H), 6.03-5.99 (m, 1H), 4.51-4.43 (m, 4H), 3.85 (s, 1H), 2.47 (s, 3H), 1.65-1.56 (m, 6H), 1.28-1.26 (m, 6H).
