Calculate Digit Verification of CAS Registry Number 108613-06:
(8*1)+(7*0)+(6*8)+(5*6)+(4*1)+(3*3)+(2*0)+(1*6)=105
105 % 10 = 5
So 108613-06-5 is a valid CAS Registry Number.

Highly efficient chemoselective N-TBS protection of anilines under exceptional mild conditions in the eco-friendly solvent 2-methyltetrahydrofuran

Pace, Vittorio,Alcantara, Andres R.,Holzer, Wolfgang

supporting information; experimental part, p. 1986 - 1989 (2011/09/16)

A straightforward chemoselective protection of anilines as N-TBS derivatives is described by using a suitable deprotonation of the amine with methyllithium in the environmentally friendly and safer substitute of THF, 2-methyltetrahydrofuran, under exceptional mild reaction conditions (0 °C, 30 min). Interestingly, the protecting group maybe cleaved efficiently by simple treatment of N-TBS-anilines with silica gel in ethanol-water.
