Reaction Steps

tert-Butyl 2-(cholestan-3-yloxy)acetate 129 (634 mg, 1.26 mmol) was taken up in DCM (4 mL) before TFA (1 mL) was added. The solution was stirred at room temperature for 90 mins. The solvent was evaporated and the residue purified using a short silica plug (SiO2: DCM to 100:5 DCM:MeOH) before being recrystallized from hexane to yield 439 mg of the white solid product (78%). 1H nmr (400 MHz, CDCl3) δ: 4.25 (s, 2H, CH2O), 3.37 (m, 1H, CHO), 1.99-0.58 (m, 31H), 0.89 (d, 3H, J=6.6, CH3), 0.85 (d, 3H, J=2.0, CH3), 0.84 (d, 3H, J=1.4, CH3), 0.80 (s, 3H, CH3), 0.64 (s, 3H, CH3).
