Participants

Reaction Steps

To the compound from Step A (735 mg, 1.16 mmol) was added methanolic ammonia (saturated at 0° C.) (20 mL). The mixture was heated in a stainless steel autoclave at 80° C. overnight, then cooled and the content evaporated in vacuo. The crude mixture was purified on silica gel using ethyl acetate/hexane as the eluent. Fractions containing the product were pooled and evaporated in vacuo to give the desired product (504 mg) as colorless foam.
