Reaction Steps

A solution of 16 (1.794 g, 2.346 mmol) in a mixture of EtOH/1N NaOH (25 mL/11.7 mL) was stirred at RT overnight. The reaction mixture was then concentrated, diluted with water and the pH was adjusted to 3-4 by addition of 1N HCl. The resulting suspension was stirred for 30 min, and the solid was collected by filtration, rinsed with water, air-dried and dried under high vacuum to afford the title compound 17 (1.217 g; mixed with the acid 18) as a pale yellow fluffy solid. MS (m/z): 665.5 and 709.5 (M+H).
