Thirty grams (1.0 mole) paraformaldehyde was added to a solution of 89.2 g. (1.0 mole) 2-amino-2-methyl-1-propanol in 600 ml. isopropanol, temperature at 45°-64°C. After all the paraformaldehyde had dissolved, the mixture was cooled to 12°C.; 92 g. (0.50 mole) anhydrous zinc acetate and 76 g. (1.0 mole) carbon disulfide were added. The reaction mixture was stirred six hours at 45°-50°C. Filtration at 5°C. gave 152.6 g. of the desired product melting with decomposition at 209°-211°C. A benzene-crystallized sample had the following analysis:
