Procedure

A solution of Example 227 (1.0 equiv) in MeOH (0.2 M solution) was treated with formaldehyde (5 equiv) and stirred at room temperature (r.t.) for 2 hours. Sodium Borohydride was added and stirred at r.t. overnight. The solvent was removed under vacuum and crude residue was purified by silica gel chromatography using the appropriate eluent (typically mixtures CHCl3/EtOH 7%/NH4OH 0.7%) to afford the title compound as a solid.
