51% With sodium sulfide nonahydrate; triethylamine In methanol 173.A methyl 2-amino-4-(hydroxymethyl)thiophene-3-carboxylate Example 173A methyl 2-amino-4-(hydroxymethyl)thiophene-3-carboxylate A solution of methyl cyanoacetate (1.18 mL, 13.28 mmol) and sodium sulfide nonahydrate (3.20 g, 13.28 mmol) in methanol (25 mL) at 0° C. was treated with 1-acetoxy-3-chloroacetone (2.0 g, 13.28 mmol). The cold bath was removed and triethylamine (1.86 mL, 13.28 mmol) was added dropwise. The solution was stirred at room temperature for 20 hours then diluted with water and extracted into ethyl acetate. The organic layer was dried over sodium sulfate, filtered, and the solvent removed under vacuum to provide the titled compound (1.25 g, 51%).
