Reaction Conditions

Reaction Steps

To (5-chloro-2-methyl-4-nitrophenyl)(morpholino)methanone (244 mg, 0.86 mmol) in ethanol (6 mL) and water (0.6 mL) was added SnCl2.2H2O (776 mg, 3.44 mmol). The mixture was heated to 65° C. for 5 h and then 2 M aqueous sodium hydroxide solution (10 mL) and DCM (10 mL) were added. The organic phase was passed through a hydrophobic frit and the solvent was removed in vacuo to give (4-amino-5-chloro-2-methylphenyl)(morpholino)methanone (203 mg, 93%) as an off-white solid. LCMS (10 cm_ESCI_Formic_MeCN): [M+H]+=255 at 2.84 min. 1H NMR (400 MHz, CDCl3): δ 7.07 (s, 1H), 6.60 (s, 1H), 4.10 (br s, 2H), 3.84-3.53 (br m, 6H), 3.36-3.24 (br m, 2H), 2.21 (s, 3H).
