Pyridine → Phenyl carbamate

Participants

Reaction Steps

A cold (3° C. to 5° C.) solution of the product of example 15 (30 mg, 0.14 mmol) and pyridine (0.014 ml, 0.17 mmol) in THF (0.7 ml) was treated with phenyl chloroformate (0.018 ml, 0.145 mmol). After stirring at RT for 2 h, the reaction was partitioned in ethyl acetate and buffer (pH 7.2). The organic layer was dried (brine, Na2SO4) and concentrated to give 43 mg of phenyl carbamate.
