Reaction Conditions

Reaction Steps

Methanesulfonyl chloride (36.45 g, 318 mmol) was added in one portion to a cold (0-5° C.) sol'n of the N-sec-butyl-2-(4-cyano-3-trifluoromethylphenoxy)-4-hydroxy-3,3-dimethylbutyramide (5, 79.0 g, 212 mmol) in 200 mL pyridine. The reaction mixture was stirred at 0-5° C. for 5 h. The reaction was quenched with 800 mL sat'd aq. NH4Cl and extracted with 1000 mL CH2Cl2. The organic phase was washed with 2N aq. HCl (3×300 mL) and then half sat'd aq. NaCl (3×300 mL). The organic was conc'd under vac (35-40° C.) to an amber gum.
