Yield:-
Reaction Conditions:
with triphenylphosphine in 1,4-dioxane;water at 100; for 2 h;
Steps:
16.A
Example 16; Part A; A reaction mixture of 3-chloro-2-methylbenzene-1-sulfonyl chloride (0.9 g, 4 mmol) and triphenylphosphine (4.19 g, 16 mmol) in dioxane/water (4:1 , 20 mL) was stirred at 100 0C for 2 hours. The mixture was diluted with water. The organic components were extracted with EtOAc twice. The combined EtOAc layers were concentrated. The residue was purified using chromatography. Compound 16-1 was eluted with 10% DCM in Hexane. Solvent evaporation afforded compound 16-1 as clear oil. 1H NMR (400 MHz, CD3OD) δ 7.17 (d, J = 8.4 Hz, 2H), 6.97 (t, J = 8.4 Hz, 1H), 3.43 (s, 1H), 2.40 (s, 3H).
