The mixture was stirred for overnight at room temperature. HCl (1%) was added, the water phase was extracted with EtOAc, the combined organic phases were washed with LiCl (5%), brine and were concentrated to give the title compound (3.6 g) MS m/z (rel. intensity, 70 eV) 196 (M+, 35), 182 (11), 181 (bp), 166 (8), 136 (10).
