Procedure
Add triethyl ethane-1,1,2-tricarboxylate (74.75 g; 1.00 equiv; 303.54 mmol; 69.41 mL) to a solution of sodium methoxide (139.6 mL of 25% wt in MeOH, 4.35M) (131.2 g; 2.00 equiv; 607 mmol) in methanol (224.8 mL), then add formamidine hydrochloride (25.19 g, 1.01 equiv; 306.58 mmol) at RT. Stir the mixture overnight. Acidify with 37% HCl at 0° C.; filter the solids and dry in vacuo overnight to give the title compound (55.89 g; 99.99% yield) as a white solid. 1H NMR (300 MHz, DMSO): 8.03 (s, 1H), 3.55 (s, 3H), 3.24-3.15 (m, 2H).
