Reaction Steps

2-Cyano-3,3-bis-methylsulfanyl-acrylic acid (the compound of formula (F), 35 g, 0.18 mol) was dissolved in 250 mL of methanol. Morpholine (the compound of formula (O), 28 mL, 0.32 mol) and triethylamine (25 mL, 0.18 mol) were added to the solution while the temperature was maintained at approximately 20° C. The reaction was warmed slightly to a temperature of between 25-27° C. and this temperature was maintained overnight. The solvents were then removed under reduced pressure taking care not to heat the reaction mixture. The resulting crude material was filtered through a short silica gel column eluting with MeOH:CH2Cl2=1:5 to afford the 3-methylsulfanyl-3-morpholin-4-yl-acrylonitrile of formula (P).
