Reaction Conditions:

in acetonitrile; for 5 h;Reflux;

Steps:

10.2

To a solution of compound 27 (5.20 g, 39.0 mmol) in 60 ml acetonitrile was added benzyl amine (3.85 g, 42.8 mmol) and heated to reflux for 5 hours. After cooled to rt, the precipitate was collected and washed with cold acetonitrile to afford compound 28 (3.2 g, 42% yield).LCMS m/z=231 [M+H]⁺ LC/MS informationColumn: Xbridge C 18 (3.5pm 4.6x50mm)Flow rate^ 1.8 mL/minUV detection wavelength: 254nm ^u Mobile phase^"- [A] is 0.05% TFA-containing aqueoous solution, and [B] is 0.05% TFA- containing acetonitrile solutionFrom 0 to 1.5 minutes, the percentage of [B] in the mobile phase was gradually increased from 5% to 100%. Thereafter a solution of 100% of [B] was used as the mobile phase.retention time= 1.31 minutes.
