A solution of 384 (672 mg, 1.99 mmol) and KOH (300 mg, 5.35 mmol) in 1:1:1 mixture of THF, MeOH and water (9 mL) was stirred at room temperature overnight. The reaction mixture was acidified to pH=4 by addition of 1M HCl and concentrated in vacuo. The residue was triturated with water and the solid was collected by filtration and dried to afford the title compound (640 mg, 99% yield). LRMS: (calc) 324.1; (found) 325.2 (M+H1)
