Procedure
Dissolve 6-(2-methoxy-4-{[2-(tetrahydropyran-4-yl)ethylamino]methyl}phenoxy)nicotinamide (Example 427) (0.612,1.59 mmol) in THF (4 mL) and few drops of methanol to form a clear solution. Add 1.27 M methanesulfonic acid (1.25 mL, 1.59 mmol) in THF. Stir for 10 minutes, then concentrate to give the title compound (0.749 g, ˜100%): TOF MS ES+ 386.2 (M+H)+, HRMS calcd for C21H28N3O4 386.2080 (M+H)+, found 386.2083, time 0.62 min; HPLC [Waters XTerra™ MS C-18 (150×4.6 mm, S-5 microm), 0.1% TFA/acetonitrile in 0.1% TFA/water at 1.0 mL/min, 5-95% over 15 min], tR=6.6 min, 100% purity.
