Procedure

To a solution of 306-a (60 mg, 0.13 mmol) (prepared according to the procedure of Compound 1) in 0.1 mL of acetic acid were added sodium acetate (39 mg, 0.48 mmol) and then formaldehyde (0.13 mL, 37% in water). The mixture was stirred at 100° C. overnight. After cooled, the mixture was adjusted to pH>7 with aqueous NaOH. The resulting precipitate was collected and purified by chromatography to afford the title compound (10 mg). MS (m/z): 392.0 (M+H)+
