Reaction Steps

To a stirred solution of (R)-3-[4-((R)-4,5-Diamino-pentyl)-phenoxy]-propane-1,2-diol (Intermediate O) (32.8 mg, 0.122 mmol) in propan-2-ol (3 ml) is added 1-(3,5-Diamino-6-chloro-pyrazine-2-carbonyl)-2-methyl-isothiourea (Intermediate A) (45.8 mg, 0.122 mmol) and the resultant reaction mixture is heated at 90° C. for 18 hours. The reaction is allowed to cool to room temperature and diluted with DMSO (1.5 ml) and purified on a Waters 3000 preparative HPLC system (Microsorb™ C18, Water (0.1% TFA): MeCN). The fractions containing product are passed through a 1 g SCX-2 cartridge which is eluted with 1:1 Water:MeCN (20 ml), MeCN (20 ml) and 7M NH3 in MeOH (20 ml). The ammonia elutions are concentrated in vacuo to afford the title compound; [M+H]+ 464
