After 16 hours the mixture was filtered and rinsed with MeOH. The MeOH solution of product was stored under N2 in the freezer and used as is for the next reaction [upon evaporation of MeOH solvent 69.9 mg (94%) of the title compound was obtained as a light yellow oil]. 1H NMR (CD3OD) δ: 7.06-7.13 (m, 1H), 6.55-6.65 (m, 3H), 2.83-2.91 (m, 2H), 2.72-2.81 (m, 2H), 2.57-2.68 (m, 1H).
