title: Synthesis and analytical profile of the new potent antibronchospastic agent 7-[(2,2-dimethyl)propyl]-1-methyl xanthine.
abstract: 7-[(2,2-Dimethyl)propyl]-1-methyl xanthine (CAS 155006-67-0, MX2/120) is a new potent antibronchospastic agent with negligible side effects. The synthesis involves the alkylation of 3-benzyl-1-methyl xanthine with neopentyl bromide followed by removal of the benzyl protecting group. Main physico-chemical properties were determined using NMR, MS, IR, UV spectra and X-ray crystal structure. A quantitative determination of substances related to MX2/120 and of residual solvents by means of HPLC and GC, respectively, is described. MX2/120 is safely stored at room temperature for a long time.
