Reaction Steps

3-[5-(2,4-Bis-benzyloxy-5-chloro-phenyl)-3-methyl-isoxazol-4-yl]-benzaldehyde (25 mg, 0.05 mmol) and morpholine (0.3 ml) were mixed with DCE (0.5 ml) in an microwave tube. Sodium triacetoxyborohydride (15 mg, 1.4 equiv) was added, the tube sealed, and nitrogen atmosphere introduced. After 1 hr more sodium triacetoxyborohydride (15 mg) was added and the reaction left stirring overnight. TLC analysis showed that the reaction had not gone to completion so a drop of acetic acid was added and the reaction again left stirring overnight after which the reaction was quenched with 1M NaHCO3 solution (7 ml) and extracted into EtOAc (5 ml). This was dried over MgSO4 and the solvent removed in vaccuo to provide 13 mg of the crude product as an off white powder which was taken over to the deprotection step.
