Compound 39 is dissolved in dry dichloromethane and deprotected using an excess of boron trichloride (1M in dichloromethane) at -78° C. and allowed to warm to -40° C. for 2 hours before quenching with methanol. The residue after workup is crystallized from water to yield 40 as a colorless crystalline solid.
