Sodium Bicarbonate → 2-Amino-6-({[2-(4-chlorophenyl)-1,3-oxazol-4-yl]methyl}sulfanyl)-4-(4-{[(4R)-2,2-dimethyl-1,3-dioxolan-4-yl]methoxy}-phenyl)pyridine-3,5-dicarbonitrile

Participants

Reaction Steps

70 mg (0.18 mmol) of the compound from Example 38A and 46 mg (0.20 mmol) of 4-(chloromethyl)-2-(4-chlorophenyl)-1,3-oxazole together with 46 mg (0.55 mmol) of sodium bicarbonate were suspended in 1.9 ml of dry DMF. The reaction mixture was stirred at RT for 20 h. The mixture was then freed from the solvent on a rotary evaporator, and the residue was purified by preparative HPLC (column: YMC GEL ODS-AQ S-5/15 μm; mobile phase gradient: acetonitrile/water 10:90→95:5).
