To a solution of compound 14.2 (14.5 mmol) in 1,4-dioxane (30 mL) was added anhydrous HCl (20 mL of a 4 N solution in 1,4-dioxane) after stirring at room temperature for 2 hours the reaction was concentrated to dryness, diluted with water and the solution adjusted to pH 8 with saturated sodium bicarbonate. The slurry was extracted several times with EtOAc and the organic layers were combined, dried and concentrated to provide [2-(2-amino-thiazol-5-yl)-ethyl]-thieno[3,2-d]pyrimidin-4-yl-amine (compound 14.3) in 88% yield.
