A solution of 397 (100 mg, 0.38 mmol), Et3N (160 μL, 1.14 mmol) and nicotinoyl chloride HCl salt (68 mg, 0.38 mmol) in DCM (2 mL) was stirred at room temperature for 1 hour and quenched by adding saturated NH4Cl sat solution (5 mL). The organic phase was separated, dried over Na2SO4, filtered and concentrated to produce a residue which was purified by flash chromatography using 5% MeOH in DCM as an eluent to afford the title compound (110 mg, 79% yield). LRMS: (calc) 367.2; (found). 368.1 (M+H1).
