Procedure

To a solution of 1.5 g (0.0094 mol) 3 and 1.01 g (0.01 mol) triethylamine in 25 ml isopropanol is added 0.91 g (0.01 mol) 3-amino-1,2-propanediol (10). The reaction mixture becomes reddish and is stirred at room temperature for 16 hours. The solvent is then removed on the rotary evaporator and the residue is purified by flash chromatography on silica gel to afford pure 11 as a yellow solid, m.p. 100°-102°.
