Reaction Steps

Under argon, 5-cyano-2-{(4S)-5-cyano-3,6-dimethyl-2-oxo-1-[3-(trifluoromethyl)phenyl]-1,2,3,4-tetrahydropyrimidin-4-yl}benzenesulfonyl chloride (52 mg, 105 μmol) was dissolved in dichloromethane (10 ml). Triphenylphosphine-polystyrene resin (capacity 1 mmol/g, 315 mg, 315 μmol, 3 eq.) was added, and the mixture was shaken for 15 h. More triphenylphosphine-polystyrene resin (1 mmol/g, 105 mg, 105 μmol, 1 eq.) was then added, and the mixture was shaken for a further 5 h. The reaction mixture was then filtered, the filtrate was concentrated under reduced pressure and the residue was dried under high vacuum. The title compound was obtained as a solid (90 mg, purity 50%, quant.) which was used without further purification in the subsequent reactions.
