Procedure

2-(1-amino-1-methylethyl)-N-[4-fluoro-2-(methylsulfonyl)benzyl]-5,6-dihydroxypyrimidine-4-carboxamide (prepared as described in WO2003035076 A1) was taken in trimethyl orthoformate and treated with 1.1 eq. of formaldehyde. The mixture was aged at room temperature for 1 hour, and then an additional equivalent of formaldehyde was added, followed by 1.5 eq. of sodium cyanoborohydride and a few drops of acetic acid. Stirring was continued for one hour more, and the mixture was purified by RP HPLC (C18, 5 μM, H2O/MeCN with 1% of TFA as eluant) to afford the title compound as a white solid.
