Ammonium Hydroxide → 4-Cyano-3-(2,4-dichlorophenyl)-5-(2-(fluoromethyl)morpholino)thiophene-2-carboxamide

Participants

Reaction Steps

A mixture of 4-cyano-3-(2,4-dichlorophenyl)-5-(2-(fluoromethyl)morpholino)thiophene-2-carboxylic acid (68.0 mg, 0.000164 mol), 33% ammonium hydroxide (33:67, ammonia:water, 0.1416 mL), EDCI (94.2 mg, 0.000491 mol) and 1-HOBT (66.4 mg, 0.000491 mol) in DCM (7 mL, 0.1 mol) was stirred at it overnight. The reaction mixture was diluted with DCM and washed with water, the organic layer was dried and purified by column chloromatography to afford 4-cyano-3-(2,4-dichlorophenyl)-5-(2-(fluoromethyl)morpholino)thiophene-2-carboxamide (38 mg, 56%). LCMS: (FA) ES+ 414, ES− 412; 1H NMR (400 MHz, d1-chloroform) δ: 7.59 (d, 1H), 7.42 (dd, 1H), 7.31 (d, 1H), 6.00 (s, 1H), 4.50 (dd, 2H), 4.12-4.08 (m, 2H), 4.00-3.78 (m, 4H), 3.36-3.25 (m, 1H), 3.22-3.15 (m, 1H)
