1-(4-(4-(8-oxa-3-azabicyclo[3.2.1]octan-3-yl)-6-(4-oxopiperidin-1-yl)-1,3,5-triazin-2-yl)phenyl)-3-(pyridin-4-yl)urea-TFA (56 mg) was taken up in methanol/tetrahydrofuran (1:1, 6 mL), and the mixture at 0° C. was treated with sodium borohydride (10 mg). After warming to room temperature, the mixture was concentrated to a residue which then was purified by HPLC to give the title compound as its TFA salt.; MS (ES+) 503.0 (M+H)+
