Reaction Steps

To a solution of methyl 2-phenylbenzoxazole-4-carboxylate (0.02 g; 0.0905 mmol) in methanol (3 ml) was added aqueous ammonia (3 ml). This was warmed to 40° C. and left to stir, whilst the reaction was monitored by TLC (1:4 EtOAc:petrol). Once all the starting material had reacted a white precipitate was formed. The solvent was removed to yield a white solid, which was recrystallised from ethyl acetate and petrol (70%).
