Reaction Steps

Intermediate 1 from step 1.1 was dissolved in 10 ml DCM and (3S)-methyl morpholine hydrochloride (276 mg, 2 mmol) was added followed by DIPEA (1.4 ml, 8 mmol) and HATU (761 mg, 2 mmol). After 1 h stirring at RT the reaction mixture was evaporated to dryness and the product was isolated by preparative HPLC.
