Sodium Bicarbonate → 2-Amino-4-(4-{[(2S)-2-{[tert-butyl(dimethyl)silyl]oxy}propyl]oxy}phenyl)-6-({[2-(4-fluorophenyl)-5-methyl-1,3-oxazol-4-yl]methyl}thio)pyridine-3,5-dicarbonitrile

Participants

Reaction Steps

100 mg (0.18 mmol) of the compound from Example 7A, 45 mg (0.20 mmol) of 4-(chloromethyl)-2-(4-fluorophenyl)-5-methyl-1,3-oxazole and 46 mg (0.55 mmol) of sodium bicarbonate in 2 ml of dry DMF are stirred at RT for 20 h. The mixture is purified directly by preparative HPLC (column: YMC GEL ODS-AQ S-5/15 μm; mobile phase gradient: acetonitrile/water 10:90→95:5). Removal of the solvent on a rotary evaporator gives the product as a white solid.
