Versuchsvorschrift
5-(3-methyl-4-isothiazolyl)-2,4-bis(methyloxy)pyrimidine (Prep 46, two batches combined, 30 mg, 0.148 mmol) was suspended in a 4M solution of HYDROCHLORIC ACID (1580 μl, 6.32 mmol) in dioxane the mixture was stirred at 90° for 2.5 hours. The mixture was allowed to cool to rt and dried (rotary) to afford a yellowish solid (0.126 mmol, yield considered quantitative assuming complete conversion to target compound).
