Yield:144432-67-7 97%
Reaction Conditions:
with pyridine for 16.5 h;Heating / reflux;
Steps:
97.A
To a refluxing solution of sulfamide (6.09 mL; 102.0 mmol) in anhydrous pyridine (109.0 mL) was added dropwise 2-methylpropane-1,2-diamine (10.7 mL; 102.0 mmol) over 30 min via syringe pump. The reaction mixture was refluxed for 16 h, then was cooled to RT and concentrated in vacuo. The residue was triturated with hexanes until the filtrate was nearly colorless. The resulting solid was dried in vacuo to give Part A compound (14.89 g, 97%) as a beige solid.
