To a solution of ethyl 2-{6-[[2-(2-methylimidazol-1-yl)ethyl](naphthalene-2-sulfonyl)amino]-3-azabicyclo[3.1.0]hex-3-yl}pyrimidine-5-carboxylate (0.211 g, 0.38 mmol) in EtOH (6 ml) in a sealed tube, was added hydroxylamine hydrochloride (0.460 g, 6.6 mmol) and sodium ethoxide (0.358 g, 5.3 mmol). The mixture was heated at 50° C. for 18 h, then water (20 ml) was added, and the product extracted with DCM (3×100 ml) and EtOAc (2×100 ml). The combined organic extracts were dried (MgSO4) and concentrated and the product purified by recrystallisation (MeOH) to give the title compound as a white solid (40 mg, 20%).
