Reaction Steps

Methyl 4-(4-carbamoyl-2-ethoxyphenylamino)-5-methylthieno[2,3-d]pyrimidine-6-carboxylate (0.025 g, 0.06 mmol) and ammonium chloride (0.250 g, 4.67 mmol) in 7N ammonia/MeOH (3.5 mL) were heated at 100° C. in a sealed-tube for 14 days. The solution was cooled and the residue filtered. The precipitate was washed with water to yield white solid (0.015 g, 63%).
