Answer
1) $BH_3.THF$ and 2) $H_2O_2$, $OH^-$ were used to synthesize the compound.
Work Step by Step
Borane adds to the double bond in a single step. Boron adds to the less hindered, less substituted carbon, and hydrogen adds to the more substituted carbon.
The boron atom is removed by oxidation, using aqueous sodium hydroxide and hydrogen peroxide (HOOH or $H_2O_2$) to replace the boron atom with a hydroxyl ($-$OH)
