Reaction Steps

A solution of the product from example 2, step (f) (0.1 g) in a mixture of alaninol (0.128 g), disopropylethylamine (0.35 ml) and N-methylpyrrolidinone (3 ml) was stirred at 100° C. for 48 h before pouring into H2O (75 ml). 2M HCl solution was then added to pH=2 and the light brown solid formed filtered and recrystallised from EtOH to afford the subtitle compound (22 mg, 19%)
