(RK1-1-22) I A solution of 4-nitrobenzenesulfonyl chloride (200 mg, 0.90 mmol), o-toluidine (106 mg, 0.99 mmol), and pyridine (79 mg, 0.08 ml, 0.993 mmol) in 5.0 mL 1,2-dichloroethane was heated to 150° C. for 10 minutes in the microwave. A 1M HCl solution was added until the pH of the mixture indicated pH=2, and the acidified aqueous layer was separated and extracted with CH2Cl2 (3×10 mL). The combined organic fractions were washed successively with brine and water then dried over Na2SO4 and evaporated to dryness to afford the title compound as a peach solid (127 mg, 47%). Mp=139-142° C. (lit. 157-159° C., Tetrahedron 62(25), 6100-6106; 2006); 1H NMR (400 MHz, CDCl3) δ 8.28 (d, J=9.0 Hz, 2H), 7.89 (d, J=9.0 Hz, 2H), 7.28-7.27 (m, 1H), 7.20-7.12 (m, 3H), 6.30 (br s, 1H), 2.01 (s, 3H).
