2,2-Dimethoxypropane → HCID 67126622, compound

Participants

Reaction Steps

To a solution of EXAMPLE 391D (1 g) and 2,2-dimethoxypropane (1.276 mL) in N,N-dimethylformamide (6.93 mL) was added para-toluenesulfonic acid monohydrate (1.451 g). The reaction was stirred for 4 hours at room temperature, triethylamine was added and the solution was concentrated by rotary evaporation. The residue was placed under high vacuum overnight to remove N,N-dimethylformamide. The residue was purified by regular phase flash column chromatography (Analogix—0-100% hexanes/ethyl acetate).
