3-Chloro-4-morpholinoaniline → 2-Butyl-4-[(3-chloro-4-morpholin-4-ylphenyl)amino]-5-phenylisothiazol-3(2H)-one 1,1-dioxide

Participants

Reaction Steps

A solution of 2-butyl-4-chloro-5-phenylisothiazol-3(2H)-one 1,1-dioxide (0.025 g, 0.083 mmol) and 3-chloro-4-morpholinoaniline (0.039 g, 0.183 mmol) in MeCN (1 ml) was heated in a microwave reactor at 130° C. for 90 mins. The product was purified by preparative HPLC (Kromasil C8, 0.1M NH4OAc/MeCN, gradient). The combined product fractions were evaporated and freeze-dried to give the title compound (0.004 mg, 9%). 1H NMR (400 MHz, CD3CN): δ 7.74 (bs, 1H), 7.29-7.24 (m, 1H), 7.20-7.15 (m, 2H), 7.12-7.08 (m, 2H), 6.80-6.75 (m, 3H), 3.76-3.71 (m, 6H), 2.85-2.81 (m, 4H), 1.85-1.76 (m, 2H), 1.52-1.42 (m, 2H), 1.00 (t, 3H); Mass Spectrum: M+H+ 476.
