A mixture of 21 mg (0.06 mmol) of methyl 9-(1-isopropyl-1H-pyrazol-5-yl)-6,7-dihydroimidazo[1,2-d]pyrido[3,2-b][1,4]oxazepine-3-carboxylate and 1.0 ml of 1 N aq LiOH in 4 ml of methanol and 4 ml of tetrahydrofuran was stirred for 6 hours. The mixture was acidified to pH 3 by addition of 1 N HCl and concentrated in vacuum. The residue was partitioned between ethyl acetate and water, the organic layer was washed with brine, dried over Na2SO4 and concentrated. Yield 17 mg. MS (ESI+): 340.1
